Glyceraldehyde-3-phosphate dehydrogenase catalyzes the phosphorylation of glyceraldehyde-3-phosphate, but unlike other glycolyti
zaharov [31]

Answer:

Answer: The correct option is C

Explanation:

The glycolytic pathway involves the oxidation of glyceraldehyde 3-phosphate.

Glyceraldehyde 3-Phosphate is oxidized by NAD+ and an inorganic phosphate is incorporated into the product to form an acyl-phosphate, 1,3-bisphosglycerate, which is an energy rich intermediate. NAD+ is reduced by the transfer of an hydride ion to form NADH. Once NADH is formed, its affinity for the enzyme decreases so that the free NAD+ displaces this NADH. The energy released by the oxidation of the substrate is conserved in the terminal phosphoanhydride bond of ATP via the formation of high energy intermediates.

Thus the oxidation/reduction is necessary to produce NADP which is required for ATP synthesis.

Examine the words. impulse, presynaptic cell, neurotransmitters, receptors, postsynaptic cell what idea can be described using a
mafiozo [28]

The idea it can describe is that it is the transfer of information from one neuron to another.

<h3>Transfer of information </h3>

The nervous system is part of the body systems that helps in the transfer of information from nerve to nerve and from nerve to muscle tissues.

The presynaptic nerve is the nerve that sends the information that is to be conveyed in form of action potential impulses.

The impulses led to the release of neurotransmitters from the terminal of the presynaptic nerve to the synapse. This binds to the receptor if the postsynaptic cell which receives the message.
