Question

Write the full forms of:
(a) DCPIP
(b) PGA
(c) RuBP
(d) PEP
(e) OAA
(f) NADP+
(g) NAD
(h) P700
(i) P680
(j) PS I
(k) PS II

Answer 1

Hint: In the first reaction of the Krebs cycle, oxaloacetate, a four-carbon molecule present in the mitochondrion, condenses with acetyl CoA to form citrate. In solution, oxaloacetate decomposes to pyruvate through decarboxylation. That is an oxaloacetic acid salt or ester.

Complete answer:
The mechanism by which energy retained in organic molecules is released to do metabolic work is known as respiration. It is a step-by-step mechanism that occurs in all living cells, is regulated by enzymes, and produces carbon dioxide and water. Enzymes regulate the majority of plant respiration. Enzymes are proteins that catalyze or influence the rate of chemical reactions without changing themselves. Each cellular reaction is catalyzed by a different enzyme. Enzymes' primary function during the respiration reaction is to aid in the transition of electrons from one molecule to another.
The full forms asked in the questions are below:
(a) DCPIP - 2,6-dichlorophenolindophenol
 (b) PGA - 3-phosphoglycerate.
(c) RuBP - Ribulose 1,5-bisphosphate.
(d) PEP - Post-exposure prophylaxis.
(e) OAA - Oxaloacetic acid.
(f) NADP+ - Nicotinamide adenine dinucleotide phosphate.
(g) NAD - Nicotinamide adenine dinucleotide.
(h) P700​ - Photosystem I primary donor.
(i) P680​ - Photosystem II primary donor.
(j) PSI - Photosystem I.
(k) PSII - Photosystem II.

Note: Photosystems are protein complexes that function and structure in photosynthesis. They work together to perform the key photochemistry of photosynthesis: light absorption and energy and electron transfer. Photosystems can be present in the thylakoid membranes of plants, algae, and cyanobacteria, which are found within the chloroplasts of plants and algae, as well as in the cytoplasmic membranes of photosynthetic bacteria.
