ng 20 Hi, Sophia Sign Out 4 of 5 Revie Part D In what way is this relevant to aerobic energy metabolism? Drag the terms on the left to the appropriate blanks in the right to complete the sentences. Terms can be used once, more than once, or not at all. Reset Help exergonic lactate pyruvate low This is relevant to aerobic energy metabolism because in at least some types of cells, lactate accumulates during periods of Hypoxia (low oxygen concentration) and must be reoxidized to pyruvate when the oxygen concentration rises again. The above calculations tell us that this reoxidation would not be possible under standard conditions, but under cellular conditions, the concentration ratios of lactate to pyruvate and of NAD to NADH must be sufficiently high to render the reaction exergonic rises high endergonic standard lowers

Answer 1

This is relevant to aerobic energy metabolism because in at least some type of cells LACTATE accumulate during period of hypoxia (Low oxygen concentration) and must be reoxydised to PYRUVATE when oxygen concentration rises. The above calculations tell us that the reoxidation would not be possible under Cellular conditions, but under Standard conditions, the ratios of lactate to pyruvate and NAD to NADH must be sufficiently high to render the reaction EXERGONIC.
