Question 5

Definition of breathing?

Answer 5

Moving air into and out of lungs

Question 6

Answer 6

When molecules spread from a high to low concentration

Question 7

Name all 4 reasons why energy is needed?

Answer 7

Chemical reactions to build larger molecules
Movement (Contracting Muscles)
Keeping warm maintaining a constant temperature
Digesting food from small intestine into blood

Question 8

Is aerobic respiration an endothermic or exothermic reaction?

Answer 8

Exothermic

Question 9

Which three things in a human body needs a lot of mitochondria?

Answer 9

Small Intestine for digestion
Sperm Cell for swimming with tail
Muscle cells for contraction

Question 10

Which part of a cell is the site of respiration?

Answer 10

Mitchondira

Question 11

Name 4 ways an alveoli is adapted for gas exchange?

Answer 11

Close to Blood supply - decrease diffusion distance
Thin walls - Short diffusion distance
Large blood supply - Increased concentration gradient
Millions of alveoli - large Surface Area

Question 12

What are alveoli?

Answer 12

Small air sacs that are the site of gas exchange
