Which metabolic pathway would be utilized for sprinting?

a) formation of acetyl CoA

b) electron transport chain

c) Krebs cycle

d) lipolysis

e) glycolysis

b) electron transport chain

Explanation:

During sprinting, muscles need a constant supply of ATPs (the energy currency of cells) to support the continuous movement. The electron transport chain is present in the inner mitochondrial membrane.

Oxidation of NADH and FADH2 through electron transport chain produces proton gradient across the membrane which in turn drives the synthesis of a large number of ATPs to support sprinting.
