respiration

Question 1

aerobic respiration

Answer 1

chemical reaction that take place in the mitochondria which use O2 to break down glucose into other nutrients to release energy

Question 2

equation respiration

Answer 2

glucose + oxygen —> CO2 + water

C6H12O6 + 6O2 —> 6CO2 + 6H2O

Question 3

anaerobic respiration

Answer 3

chemical reaction in cells that break down glucose to release energy without using oxygen. less efficient
happens in cytoplasm
happens with high intensity

Question 4

equation anaerobic respiration
( for yeast)

Answer 4

glucose —> alcohol + carbondioxide

C6H12O6 —> 2C5H5OH + 2CO2

Question 5

equation anaerobic respiration
(for humans)

Answer 5

glucose —> lactic acid

Question 6

terrestial

Answer 6

diffusion from the air

Question 7

aquatic

Answer 7

diffusion from the water

Question 8

alveoli structure

Answer 8

where gas exchange happens
tiny capillaries wrap around each
permeable
thin
close to transport system to take gases to and from
large surface area
good supply to O2

Question 9

gas exchange in humans step 1

Answer 9

air enters through the mouth or nose. Goblet cells produce liquid made of water and mucus which traps dust

Question 10

gas exchange in humans step 2

Answer 10

air passes through the trachea.

Question 11

gas exchange in humans step 3

Answer 11

air enters the thorax. trachea splits into 2 bronchi. 1 bronchus goes to the lungs then splits into many bronchioles

Question 12

gas exchange in humans step 4

Answer 12

air enters the alveoli
