5 Questions
Cellular respiration is the process by which energy in the form of ATP is released from food molecules.
True
The energy stored in food is converted into adenosine triphosphate (ATP) before being used by the body.
True
ATP is composed of a sugar (ribose) bound to an organic base (adenine) and a chain of two phosphate groups.
False
The ATP molecule transfers the energy captured during respiration to the many sites that use energy in the cell.
True
Cells use ATP through exergonic reactions, where a phosphate group split from ATP activates a protein, catalyzing an exergonic process.
False
