Respiration

Question 1

define Aerobic respiration

Answer 1

the conversion of glucose and oxygen into carbon dioxide and water to release energy

Question 2

what is the chemical equation for aerobic respiration

Answer 2

glucose + oxygen →carbon dioxide + water

Question 3

true or false: aerobic respiration doesn’t occur in white blood cells

Answer 3

false, it occurs in all cells except red blood cells

Question 4

what are produced during aerobic respiration? which of these are waste?

Answer 4

energy is released as ATP, as well as carbon dioxide and water which are waste products

Question 5

where in the cell does AEROBIC respiration occur?

Answer 5

the mitochondria

Question 6

what is ATP used for?

Answer 6

1. making cells
2. contracting muscles
3. warmth

Question 7

what is the word equation for lactate fermentation

Answer 7

glucose→ lactic acid

Question 8

where does lactate fermentation occur

Answer 8

in the cytoplasm

Question 9

when does lactate fermentation occur

Answer 9

when your heart rate cant increase fast enough to meet the oxygen demand (oxygen debt)

Question 10

what form of anaerobic respiration takes place in the body

Answer 10

lactate fermentation

Question 11

why do athletes breathe heavily after a race

Answer 11

the body needs oxygen to react with the lactic acid and stop cramping

Question 12

julia runs a race. would the concentration of lactic acid in her blood increase or decrease as the race went on? WHY?

Answer 12

it would increase. the body would be in oxygen debt so it needs to respire anaerobically. this would mean that lactic acid would be produced. sine there is no oxygen to get rid of it it builds up

Question 13

where does alcoholic respiration occur

Answer 13

plants and microorganisms

Question 14

what is the word equation for alcoholic respiration

Answer 14

glucose→ carbon dioxide + ethanol

Question 15

what does the red blood cell do?

Answer 15

transports O2, contains haemoglobin

Question 16

what component of blood helps with clotting

Answer 16

elatelets

Question 18

What is the primary function of the lungs?
