A dog chasing a rabbit needs energy from the food it has eaten. Which process makes the most usable energy for the dog?
A
Electron transport chain
B
Photosynthesis
C
Citric acid cycle
D
Glycolysis
Explanation: 

Detailed explanation-1: -glycolysis. Answer: Option (C) is the correct answer.

Detailed explanation-2: -The electron transport chain is a series of four protein complexes that couple redox reactions, creating an electrochemical gradient that leads to the creation of ATP in a complete system named oxidative phosphorylation. It occurs in mitochondria in both cellular respiration and photosynthesis.

Detailed explanation-3: -As electrons move down the chain, energy is released and used to pump protons out of the matrix, forming a gradient. Protons flow back into the matrix through an enzyme called ATP synthase, making ATP. At the end of the electron transport chain, oxygen accepts electrons and takes up protons to form water.
