CELL RESPIRATION

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The energy needed to win a 1-minute footrace is produced mostly by ____
A
lactic acid fermentation
B
cellular respiration
C
using up stores of ATP
D
breaking down fats
Explanation: 

Detailed explanation-1: –The energy needed to win a 1-minute foot race comes primarily from which process? LACTIC ACID FERMENTATION. What is needed to convert pyruvic acid into lactic acid? What happens during fermentation?

Detailed explanation-2: -Anaerobic respiration results in the production of 2 ATP molecules.

Detailed explanation-3: -During formation of lactic acid by anaerobic respiration 2 molecules of ATP are produced.

Detailed explanation-4: -The amount of useable energy produced by lactic acid fermentation is two ATP. All types of fermentation start with the process of glycolysis. During glycolysis four ATP are create, but two ATP are needed during the initial chemical reactions. That means that each glucose molecule produces two net ATP during glycolysis.

Detailed explanation-5: -Fermentation only produces two ATP per glucose molecule through glycolysis, which is much less ATP than cellular respiration.
