The structure that is considered the energy currency of the body is adenosine triphosphate (ATP). The correct answer is the last option.

ATP stands for adenosine triphosphate, which is the body's primary energy source. This molecule is composed of adenosine, a nitrogen-containing compound, and three phosphate groups, which are responsible for ATP's high energy content. ATP is an energy-rich molecule that is used by the body's cells to power a variety of cellular processes. The energy that is stored in ATP is released when one of the phosphate groups is broken off, a process that generates energy that can be used to power cellular processes like muscle contraction, nerve impulses, and biochemical reactions.

Electron transfer from Photosystem II to Photosystem I occurs in light-dependent reactions, involving the transfer of electrons from a high-energy molecule in Photosystem II to a low-energy molecule in Photosystem I. This electron transfer is facilitated by a series of proteins that shuttle electrons between the two photosystems and generates a proton gradient, which provides the energy for ATP synthesis.

The electron transfer pathway from Photosystem II (PS II) to Photosystem I (PS I) in light-dependent reactions is described below:

The PS II complex, which is found on the thylakoid membranes, absorbs light energy and energizes electrons that travel to Pheophytin (Ph). The Ph passes its energized electron to Quinone A (QA). As a result, the QA molecule gets reduced to Quinol A (QA-).

The reduced QA- molecule transports the electrons to the cytochrome b6f complex through a series of redox reactions. The movement of electrons through cytochrome b6f is coupled with the transfer of protons from the stroma into the lumen, creating a proton gradient between the two regions.

The protons that are moved through the thylakoid membrane during this process are utilized to power the ATP synthase enzyme, which produces ATP.

The electrons are subsequently transferred to Plastoquinone B (PQ). PQH2 transports electrons to the Photosystem I complex (PS I), where they are energized by another photon of light. These electrons are transported to the ferredoxin molecule, where they are used to reduce NADP+ to NADPH.

If meiosis II proceeds normally, each of the four gametes that result from that meiosis will have 20 chromosomes.

If a homologous pair undergoes non-disjunction during meiosis, then two cells will have an extra chromosome, and the remaining two cells will have one chromosome fewer.

In the first meiotic division of a germ cell, if a single homologous pair undergoes non-disjunction in meiosis, it means that they do not separate correctly.

Non-disjunction is defined as the failure of chromosomes to separate during cell division, resulting in an abnormal distribution of chromosomes in the daughter nuclei.

When non-disjunction occurs during meiosis I, the chromosomes remain attached, and all four daughter cells will have an abnormal number of chromosomes.

Non-disjunction can result in cells that have too many or too few chromosomes. If the pair of chromosomes does not separate properly in meiosis I, it will result in two cells having an extra chromosome, and two cells will lack one chromosome.

These cells are called aneuploid cells. An aneuploid cell is a cell that does not contain a multiple of the haploid chromosome number.

The correct statement(s) about absorption is (D) Amino acid transport is linked to sodium transport.

Amino acids are transported across the villus epithelium in the small intestine, and this process is linked to sodium transport.

Amino acids, not proteins, are absorbed; proteins rely on prior digestion to amino acids. Most absorption of amino acids occurs in the jejunum; there is a lesser contribution from the ileum.

Amino acids are absorbed by a co-transport mechanism with sodium ions. Both sodium ion and amino acid combine with a cell surface protein receptor.

There are different receptors for the groups: neutral amino acids, basic amino acids, acidic amino acids

In addition, certain amino acids may have there own specific transporter e.g. proline. The receptor then conveys both molecules to the inside of the cell.

The energy for this transport is derived from the concentration gradient for sodium across the cell membrane. Na-K ATPase transporters actively and continuously pump sodium ions outwards to maintain the gradient.

There must be at least 20 different tRNA molecules in a cell in order to form proteins. Each of the tRNA molecules has a unique anticodon that pairs with a codon of mRNA and a unique amino acid-binding site that pairs with a particular amino acid. This is necessary for the formation of proteins.

The minimum number of different tRNA molecules that must exist in a cell is 20, as there is one specific tRNA molecule for each of the 20 amino acids. Each tRNA molecule carries the correct amino acid to the ribosome, which is necessary for the formation of proteins.

The structure of tRNA molecules consists of an amino acid-binding site and an anticodon region. The anticodon region of each tRNA molecule is complementary to a codon of mRNA, and the amino acid-binding site is able to interact with an amino acid. The codons of mRNA direct the ribosome to the appropriate tRNA molecule that corresponds to a particular amino acid.

Therefore, since there are 20 amino acids, 20 different tRNA molecules must exist in a cell in order to pair with each of the codons of mRNA. This ensures that the correct amino acid is available for the formation of proteins. Without the correct tRNA molecule, the ribosome would not be able to bring the correct amino acid to the site of protein synthesis.

Motor units influence the strength of the whole muscle directly whereas the precision of muscle contraction is inversely affected by the size of the motor unit.

A motor unit consists of a motor neuron and the muscle fibers that it activates. The strength of whole muscle contraction is determined by the number of motor units that are activated.

If more motor units are activated, the muscle contraction will be stronger. If fewer motor units are activated, muscle contraction will be weaker. This is known as the size principle, which states that smaller motor units are activated first, followed by larger motor units as more force is needed.

The size of a motor unit influences the precision of muscle contraction (control) by determining the number of muscle fibers that are controlled by a single motor neuron.

Small motor units control a small number of muscle fibers, which allows for fine control and precision. Large motor units control a larger number of muscle fibers, which allows for greater force production but less precision.
