6

During cellular respiration, how many molecules of CO₂ will be produced from one molecule of glucose?

G3P

Energy is invested into the process of glycolysis in the form of 2 ATP molecules, which contribute one phosphate each to a pair of 3-carbon intermediates of glucose called

the synthesis of ATP.

The flow of H⁺ from the intermembrane space into the matrix will cause

inputs of glycolysis

ATP

During the energy-investment step of glycolysis, Blank______ is invested to start the reaction.

A phosphate

During the energy-harvesting step of glycolysis, what get passed to ADP?

NAD⁺ is required for glycolysis to continue.

It is important that NAD⁺ is regenerated during fermentation because

cristae

Short, fingerlike projections formed by the folding of the inner membrane of mitochondria are called
