ATP Synthesis

Question 1

On average humans use more than 50 kg of ATP in a day but only have a maximum of ~ 200g of ATP in their body at any given time

Organisms …………….build up large stores of ATP and it rarely passes through the………………

Answer 1

cannot

cell surface membrane

Question 2

This means the cells must make ATP as and when they

Answer 2

need it

Question 3

ATP is formed when

catalysed by enzyme

Answer 3

ADP is combined with an inorganic phosphate (Pi) group by the enzyme ATP synthase

Question 4

This is an energy-……………….. reaction

Answer 4

requiring

Question 5

…………………..as a waste product (therefore ATP synthesis is a condensation reaction)

Answer 5

Water is released

Question 6

ATP is made during the reactions of

Answer 6

during the reactions of respiration and photosynthesis

All of an animal’s ATP comes from respiration

Question 7

ATP can be made in two different ways

Answer 7

Substrate-linked phosphorylation (occurs in the glycolysis stage of respiration)

Chemiosmosis (occurs in the electron transport chain stage of respiration)
