Question

compare and contrast NAD+ and NADP+

how many CO2 molecules are released during the breakdown of 4 glucose molecules

^^glycolysis and cellular respiration

Answer 1

NAD+ and NADP+ are the coenzymes involved in oxidation-reduction reaction. They are abundant in cells.

NAD+(nicotinamide adenine dinucleotide)	NADP+(nicotinamide adenine dinucleotide phosphate)
Involved in cellular respiration	Used in photosynthesis
Doesn’t contain Phosphate group	Contains phosphate group
Involved in glycolysis, fatty acid synthesis etc	Used in calvin cycle, PPP pathway etc
NADH is the reduced form	NADPH is the reduced form
NAD+ is a oxidizing agent	NADP is mostly used in catabolic pathways

QUESTION 2

answer- Release of energy during cellular respiration

C6H2O6 + 6O2 ---->6CO2 + 6H2O

One glucose molecule give 6 carbon dioxide molecule. therefore, 4 glucose molecule gives 24 carbon dioxide molecules.

During glycolysis,

one molecule of glucose gives two molecules of pyruvate which is converted to acetyl coA with release 2 carbon dioxide molecule.

glycolysis, 1 molecule of glucose gives 2 carbon dioxide. 4 glucose molecules gives 8 molecules of carbon dioxide.
