Cellular Respiration

Question 1

Adenosine Triphosphate (ATP) is made up of what molecules?

Answer 1

Adenosine, Ribose, Triphosphate group

Question 2

What does the cell need energy for?

Answer 2

for mechanical work, to make new materials, for (active) transport, to maintain order

Question 3

What are the two important compartments of the mitochondria for respiration

Answer 3

Matrix and Inner membrane

Question 4

Why is the inner membrane of the mitochondria highly folded?

Answer 4

Folds are called christae. For larger surface area so that more electron transport chain enzymes and ATP synthase can be present (and therefore more ATP can be produced)

Question 5

What are the 3 stages of cellular respiration?

Answer 5

Glycolisis, Pyruvate Oxidation & Citric Acid Cycle, Oxidative Phosphorylation

Question 6

What are the two parts to oxidative Phosphorylation?

Answer 6

Electron transport chain (electrons from NADH and FADH2) and chemiosmosis (ATP production)

Question 7

What does ATP enable?

Answer 7

The controlled release of energy. If it was not done in this controlled way, the excess heat would damage the cell.

Question 8

If a cell is a high energy cell, what will it have more of??

Answer 8

More mitochondria in the cell in order to produce more ATP. Eg. muscle cells
