CHAP 642 18 QUESTION 1 a result of glyeolysis, glucose splits intomolecules of pyruvic acid. used for this process to hegin, and molecules of ATP were originally ATP molccules . Hydrogens and electrons released from glucose were produced, therefore the net gain of ATP available to the cell during this process were used to reducc . If pyruvic acid is acted upon by acetyl coenzyme A, and a molecule of each. The two-carbon acotyl groups can then be transported to the site of the Krebs cycle, where they are utilized through a series of to r .. it is converted into is rcleased for mediated steps to produce l molecules of reduced NAD,molecules of reduced FAD , and two additional I as phosphorylation. The clectrons bound by the coenzymes are then via substratc-level passed to cytochromes in theand the hydrogens are surface of the membrane. The released to the hydrogens then pass through oxygen to form transport, coupled with the passage of hydrogens through ATP synthase, drives the formation of , where thcy bond with . The releasc of energy by electron new ATP of the ATP molecules must be molecules. In animals used for the transport of NADH+II across the mitochondrial membrane, reducing the total number from toExplanation / Answer
Ans. please consider the fill ups in a serial order, check answer line by line as:
2 molecules of pyruvic acid
4 ATP to begin the process
2ATP are used up
2ATP net gain
reduce NAD to NADH
pyruvate is acted upon by pyruvate dehydrogenase complex
molecule of NADH is released
enzyme mediated steps, 6 molecules of reduced NAD
2 molecules of reduced FAD as
FADH2 and two additional ATP
cytochromes in the matrix
hydrogen are released to the inner
hydrogen the pass through oxygen
oxygen then forms water
drives the formation of 34 ATP
In animals, 2 of the ATP molecules
reducing the total number
from 38ATP to 36ATP
