If a cell is able to synthesize 30 atp molecules for each molecule of glucose completely oxidized to carbon dioxide and water, approximately how many atp molecules can the cell synthesize for each molecule of pyruvate oxidized to carbon dioxide and water?
possible answers:
a. 0
b.1
c. 12
d. 14
e. 15

E =15

Explanation:

Basically, 1 molecule of glucose  molecule after substrate level phosphorylation in glycolysis gives 2 molecules of 3 carbon compounds called pyruvate, for complete oxdation .

                           1 GLUCOSE molecule       ⇒ 2Pyruvates.

Each pyruvate molecule can produce  15 ATPs .( in citric acid cycle, and oxidative phosphorylation),.Since 30ATPs were produced,;each pyruvate molecule  must have contributed 15 ATPs each for a total of 30ATPs

hydroxyl -oh

alcohols, always polar, can form hydrogen bonds with h2o molecules

carboxyl -cooh  

cargoxylic acids, has acidic properties which is a source of hydrogen ions, found in cells in ionized for with a charge of oh-1

carbonyl > co

ketone if within skeleton, aldehyde if group is at the end of skeleton, k & a may be structural isomers, it determines 2 sugars (ketose & aldose)

amino -nh2

amines, acts as a base, it can pick up h+ ions from surrounding solution, ionized with charge of 1+

methyl ch2

addition to rna/dna affects and gene expression

phosphate -opo3 ²⁻

organic phosphates, contributes to negative charge to, molecule that it is a part of, and potential to react with h20

sulfhydryl -sh

thiols, cross-linking stabilize the protein, and it is structure
