Which would probably have the greatest effect on a protein's function—a change to the primary, secondary, or tertiary structure? Explain your answer.
Answer:
There are 20 different standard L-α-amino acids used by cells for protein construction. Amino acids, as their name indicates, contain both a basic amino group and an acidic carboxyl group. This difunctionality allows the individual amino acids to join in long chains by forming peptide bonds: amide bonds between the -NH2 of one amino acid and the -COOH of another. Sequences with fewer than 50 amino acids are generally referred to as peptides, while the terms, protein and polypeptide, are used for longer sequences. A protein can be made up of one or more polypeptide molecules. The end of the peptide or protein sequence with a free carboxyl group is called the carboxy-terminus or C-terminus. The terms, amino-terminus and N-terminus, describe the end of the sequence with a free α-amino group.
The amino acids differ in structure by the substituent on their side chains. These side chains confer different chemical, physical, and structural properties to the final peptide or protein. The structures of the 20 amino acids commonly found in proteins are shown in Figure 1. Each amino acid has both a one-letter and three-letter abbreviation. These abbreviations are commonly used to simplify the written sequence of a peptide or protein.
figure1-Protein-Structure
Depending on the side-chain substituent, an amino acid can be classified as being acidic, basic or neutral. Although 20 amino acids are required for synthesis of various proteins found in humans, we can synthesize only ten. The remaining 10 are called essential amino acids and must be obtained in the diet.
The amino acid sequence of a protein is encoded in DNA. Proteins are synthesized by a series of steps called transcription (the use of a DNA strand to make a complimentary messenger RNA strand – mRNA) and translation (the mRNA sequence is used as a template to guide the synthesis of the chain of amino acids which make up the protein). Often, post-translational modifications, such as glycosylation or phosphorylation, occur which are necessary for the biological function of the protein. While the amino acid sequence makes up the primary structure of the protein, the chemical/biological properties of the protein are very much dependent on the three-dimensional or tertiary structure.
A change to the PRIMARY structure WILL HAVE the greatest effect on a protein's function.
The primary structure of a protein refers to the linear sequence of amino acids within a polypeptide chain.A change in the protein primary structure will change protein properties and likely will also alter their functions.The secondary structure of a protein refers to the specific arrangement of groups of amino acids. The most common types of secondary structures in proteins include alpha helix and beta sheets.The tertiary structure refers to the three-dimensional shape of the protein. There are two major main classes of protein tertiary structure: fibrous and globular.The quaternary structure refers to the association of different protein subunits to form a multimeric protein.In conclusion, a change to the PRIMARY structure WILL HAVE the greatest effect on a protein's function.

Krebs cycle
Answer:
D. Krebs Cycle
Explanation:
Hope this helped.
The answer to this question is Krebs Cycle.
Krebs cycle. A series of chemical reactions that occur in most aerobic organisms and are part of the process of aerobic cell metabolism, by which glucose and other molecules are broken down in the presence of oxygen into carbon dioxide and water to release chemical energy in the form of ATP.
Overview of the Krebs or citric acid cycle, which is a series of reactions that takes in acetyl CoA and produces carbon dioxide, NADH, FADH2, and ATP or GTP.
The Krebs cycle itself actually begins when acetyl-CoA combines with a four-carbon molecule called OAA (oxaloacetate). This produces citric acid, which has six carbon atoms. This is why the Krebs cycle is also called the citric acid cycle.May 15, 2020

If the DNA sequence was a AGC what would the mRNA sequence be?
Answer:
DNA utilizes four bases, adenine (A), guanine (G), cytosine (C), and thymine (T), in its code. RNA also uses four bases. However, instead of using 'T' as DNA does, it uses uracil (U). Therefore, if your DNA sequence is 3' T C G T T C A G T 5', the mRNA sequence would be 5' A G C A A G U C A 3'.

F- The car with the smaller mass will require less force to stop than the car with the larger mass.
G- The car with the larger mass will maintain its velocity while traveling down the hill.
H- The car with the smaller mass will take longer to stop than the car with the larger mass.
J- The car with the larger mass will have less inertia than the car with the smaller mass.
Please mark answer and Give explanation
Answer:
F
Explanation: The car with the smaller mass will require less force to stop than The car with the larger mass that is it
The car with the smaller mass will require less force to stop than the car with the larger mass.
What is law of inertia?The law of inertia or Newton's first law of motion states that an object at rest or uniform motion in a straight line will continue in that form unless it is acted upon by an external force.
This law is called the law of inertia because it depends on mass of the object.
The object with more mass will required more force to be stopped while the object with less mass will require less force to be stopped.
Thus, the car with the smaller mass will require less force to stop than the car with the larger mass.

what are acquired traits why are the streets generally not inherited over generation explain
Answer:
Acquired traits are due to changes in the life style, injury, loss of body parts, disuse of some body parts. These are the traits which occur in the somatic cells. Changes in the somatic cells are not passed on to the offspring belonging to next generation. Hence acquired traits cannot be passed on to next generation.

What molecules will carry the electrons to the electron transport chain?
Answer:
electron and nuetrons
The molecules NADH and FADH₂ will carry the electrons to the electron transport chain.
These electron carrier molecules (NADH and FADH₂) are produced during the breakdown of glucose and other energy-rich molecules in the preceding steps of cellular respiration. They carry the high-energy electrons derived from these molecules to the electron transport chain, which is embedded in the inner mitochondrial membrane in eukaryotic cells.
The electrons passed through the electron transport chain ultimately combine with molecular oxygen to form water, which is the final electron acceptor in the chain.
