respiration

Question 1

ATP

Answer 1

Stores and transfers energy in cells. Created through respiration in the mitochondria. Obtained through the breakdown of food and made up of three phosphate attached to adenosine (amino acid).

Question 2

How does ATP release energy?

Answer 2

Through respiration ATP is hydrolysed to ADP by breaking a bond between one phosphate. This results in two phosphates attached to adenosine. This releases energy.

Question 3

Aerobic respiration

Answer 3

With sufficient supply of oxygen

Question 4

Anaerobic respiration

Answer 4

Without oxygen

Question 5

Aerobic respiration equation

Answer 5

Glucose + Oxygen – Carbon dioxide + Water +ATP

C6H12O6 + 6O2 – 6CO2 + 6H2O (+ATP)

Question 6

Anaerobic respiration

Answer 6

Glucose – Latic acid + ATP (less)

Question 7

Why is ATP efficient?

Answer 7

Releases energy in small manageable amounts.
Broken down in one simple step (one bond broken).
Immediate energy available.
Can be easily made again.
