Respiration

Question 1

They both happen in the..

Answer 1

Mitohondria

Question 2

When do living things respire

Answer 2

All of the time

Question 3

What type of reaction is aerobic resp

Answer 3

Exothermic so they can continuously release energy

Question 4

Formula for aerobic resp

Answer 4

Oxygen + Glucose -> (energy) + carbon dioxide + water

Question 5

Exothermic reaction

Answer 5

Gives out energy

Question 6

Endothermic reaction

Answer 6

Takes in energy

Question 7

What is aerobic resp

Answer 7

When oxygen diffuses from alveoli into bloodstream
Glucose diffuses out of small intestine into digestive system and into capillaries in bloodstream and then into respiring cells.

Carbon dioxide is waste product of diffusion and goes out of cells into bloodstream and then into alveoli to be breathed out of the body

Question 8

Cardiac output

Answer 8

Volume of blood circulated by heart per min

Question 9

Stroke volume

Answer 9

Volume of blood pump per beat

Question 10

Cardiac output equation

Answer 10

Cardiac output = stroke vol x heart rate

Cm3/min Cm3 bpm

Question 11

What happens when we reach max breathing rate and cardiac output

Answer 11

We cant supply oxygen any quicker so cant release more energy in aerobic resp. Therefore we begin to respire anaerobically

Question 12

What is EPOC

Answer 12

The extra oxygen needed to break down lactic acid after anaerobic resp. Its called the “excess post exercise oxygen consumption”
