Cellular Respiration and ATP

These flashcards cover key concepts related to cellular respiration, ATP structure, and energy transfer.

What are the main electron carriers in cellular respiration?

NAD+ and FAD.

What is the reduced form of NAD+?

NADH.

What is the reduced form of FAD?

FADH.

What is the nitrogen base of ATP?

Adenine.

What is the five carbon sugar present in ATP?

Ribose.

How many phosphate groups are there in an ATP molecule?

3.

What attribute of ATP contributes to its high potential energy?

The clustered phosphate groups with charge repulsion.

What reaction breaks the bonds of ATP?

Hydrolysis.

What bond, when broken, releases energy from ATP?

Phosphoanhydride bond between the beta and gamma phosphate groups.

What does ATP turn into when paired with H2O?

ADP + Pi.

Is ATP hydrolysis an exergonic reaction?

True.

What occurs in a coupling reaction?

Energy from ATP hydrolysis is paired with an endergonic reaction.

What high energy molecule is converted into ATP?

Glucose.

How is ATP generated from glucose?

Through aerobic cellular respiration.

What is a redox reaction?

A chemical reaction involving the transfer of electrons, where one substance is oxidized and another is reduced.

What does it mean for a molecule to be reduced?

It gains electrons and energy.

What happens to a molecule during oxidation?

It loses electrons

What happens to the energy of a molecule during oxidation?

It decreases.
