"Explain how chemical energy for use in the cell is generated by electron transport and chemiosmosis"
PLEASE HELP!!
Answer:
Explanation:
The electron-carrier proteins are arranged in the inner mitochondrial wall. A dehydrogenase enzyme (think of it as the first protein of the electron-transport chain) oxidises NADH2 (which is the reduced coenzyme NAD) and/or FADH2 (reduced coenzyme FAD). The energy from the oxidation process is used to pump hydrogen ions from the matrix to the inter-membrane space of the mitochondrion. Because of this, gradient of hydrogen ion concentration builds up across the inner mitochondrial membrane, which generates a potential difference across the membrane. The protons then flow back to the matrix through an enzyme called ATP synthase (also called ATPase). (This is called chemiosmosis because a chemical substance (H+) moves across a membrane, down the concentration gradient.) This releases energy needed for the ATP synthase to phosphorylate ADP, i.e. make ATP (chemical energy for use in the cell) from ADP and inorganic phosphate.

How would larger substances like proteins get into or out of the cell membrane?
Answer:
It is possible for large molecules to join a cell by a method called endocytosis, where a small piece of the cell membrane surrounds the particle and is brought into the cell. If the particle is solid, endocytosis is also dubbed phagocytosis. If fluid droplets are taken in, the process is called pinocytosis.

might be like the system the ants use to transport food?
Answer
Ants bring food to one location, the food they bring in helps to make more ants and keep the cycle going. Like ants our blood cells break down the nutrients we get from food into nutrients and other beneficial things we need in our body, those same blood cells as well as new ones, use energy to make more cells. This almost neverending cycle helps sustain our human bodies so we can keep living and create more humans.

2. Describe the different ways that a system can be efficient. For example, time
efficiency, economic efficiency, and resource efficiency.
What Is Economic Efficiency?
Economic efficiency is when all goods and factors of production in an economy are distributed or allocated to their most valuable uses and waste is eliminated or minimized.
KEY TAKEAWAYS
Economic efficiency is when every scarce resource in an economy is used and distributed among producers and consumers in a way that produces the most economic output and benefit to consumers.
Economic efficiency can involve efficient production decisions within firms and industries, efficient consumption decisions by individual consumers, and efficient distribution of consumer and producer goods across individual consumers and firms.
Pareto efficiency is when every economic good is optimally allocated across production and consumption so that no change to the arrangement can be made to make anyone better off without making someone else worse off.

Economic Efficiency
Understanding Economic Efficiency
Economic efficiency implies an economic state in which every resource is optimally allocated to serve each individual or entity in the best way while minimizing waste and inefficiency. When an economy is economically efficient, any changes made to assist one entity would harm another. In terms of production, goods are produced at their lowest possible cost, as are the variable inputs of production.
Some terms that encompass phases of economic efficiency include allocative efficiency, productive efficiency, distributive efficiency, and Pareto efficiency. A state of economic efficiency is essentially theoretical; a limit that can be approached but never reached. Instead, economists look at the amount of loss, referred to as waste, between pure efficiency and reality to see how efficiently an economy functions.
Economic Efficiency and Scarcity
The principles of economic efficiency are based on the concept that resources are scarce. Therefore, there are not sufficient resources to ensure that all aspects of an economy function at their highest capacity at all times. Instead, scarce resources must be distributed to meet the needs of the economy in an ideal way while also limiting the amount of waste produced. The ideal state is related to the welfare of the population with peak efficiency also resulting in the highest level of welfare possible based on the resources available.
Efficiency in Production, Allocation, and Distribution
Productive firms seek to maximize their profits by bringing in the most revenue while minimizing costs. To do this, they choose the combination of inputs that minimize their costs while producing as much output as possible. By doing so, they operate efficiently; when all firms in the economy do so, it is known as productive efficiency.
Consumers, likewise, seek to maximize their well-being by consuming combinations of final consumer goods that produce the highest total satisfaction of their wants and needs at the lowest cost to them. The resulting consumer demand guides productive (through the laws of supply and demand) firms to produce the right quantities of consumer goods in the economy that will provide the highest consumer satisfaction relative to the costs of inputs. When economic resources are allocated across different firms and industries (each following the principle of productive efficiency) in a way that produces the right quantities of final consumer goods, this is called allocative efficiency.
Finally, because each individual values goods differently and according to the law of diminishing marginal utility, the distribution of final consumer goods in an economy are efficient or inefficient. Distributive efficiency is when the consumer goods in an economy are distributed so that each unit is consumed by the individual who values that unit most highly compared to all other individuals. Note that this type of efficiency assumes that the amount of value that individuals place on economic goods can be quantified and compared across individuals.
Economic Efficiency and Welfare
Measuring economic efficiency is often subjective, relying on assumptions about the social good, or welfare, created and how well that serves consumers. In this regard, welfare relates to the standard of living and relative comfort experienced by people within the economy. At peak economic efficiency (when the economy is at productive and allocative efficiency), the welfare of one cannot be improved without subsequently lowering the welfare of another. This point is called Pareto efficiency

Which is the next structure to contact air after it passes from the nose to the nasal cavity?
the pharynx
the larynx
the bronchus
the trachea
Answer:
the pharynx
Explanation:
edge 2022
The next structure to contact air after it passes from the nose to the nasal cavity is the pharynx.
What is pharynx?The pharynx is a muscular tube located behind the nasal cavity and mouth, connecting them to the esophagus and larynx. It serves as a shared pathway for both the respiratory and digestive systems.
In terms of the respiratory system, the pharynx plays a crucial role in the passage of air from the nasal cavity or mouth to the larynx. It acts as a conducting tube, allowing the air to flow smoothly towards the lower respiratory tract. The pharynx also houses the tonsils, which are part of the body's immune system and help protect against pathogens.
Additionally, the pharynx is involved in the process of swallowing. It facilitates the movement of food and liquid from the mouth to the esophagus, ensuring that they enter the digestive system and not the respiratory system.
Overall, the pharynx is a vital structure that serves as a passageway for both air and food, contributing to the proper functioning of the respiratory and digestive systems.

What is the prey-predator relationship?
In an ecosystem, there are predators and prey. If the predator population grows, they will consume more prey more quickly, causing the prey population to decline rapidly. When there are more prey in an ecosystem, it would be advantageous for the predator, and after some time, the prey will decrease in number and the predator will increase.
Salmon, mouth bass, and lake trout feed on smelt in the lake. Lake trout populations increased in the late 1980s, and as a result, they began feeding on smelt. The other two predators were also affected. The salmon population declined for some time, but later their number increased too. The mouth bass population got affected a lot, and their number kept on declining. The other two species chose different prey and multiplied.
Hence, for some time, the salmon population declined. Option A is correct.

How do plants return nitrógen to the soil
Answer:
I think when plants decompose, nitrogen gets realesed back into the soil.
Answer:
Plant and animal wastes decompose, adding nitrogen to the soil. Bacteria in the soil convert those forms of nitrogen into forms plants can use. Plants use the nitrogen in the soil to grow. People and animals eat the plants; then animal and plant residues return nitrogen to the soil again, completing the cycle.
