respiration

Question 1

what is respiration

Answer 1

the process of releasing energy from the breakdown of glucose

Question 2

energy made by ___________ cant be used directly by cells so it makes a substance called _____ which acts as an __________ ________

Answer 2

respiration, ATP, energy store

Question 3

what are the cellular processes that energy released by respiration makes (3)

Answer 3

metabolic processes, contracting muscles and maintaining a steady body temperature

Question 4

respiration involves a series of different _________ reactions which are controlled by __________ so the rate of respiration is affected by both _________________ and _____

Answer 4

chemical, enzymes, temperature, pH

Question 5

what are the 2 types of respiration

Answer 5

aerobic (with oxygen) and anaerobic (without)

Question 6

equation of aerobic respiration

Answer 6

glucose + oxygen —>
carbon dioxide + water

Question 7

why is aerobic respiration the most efficient way to release energy from glucose

Answer 7

as it produces lots of ATP

Question 8

why is anaerobic respiration less effective than aerobic respiration

Answer 8

as the glucose is only partially broken down which limits the number of ATP molecules prouduced

Question 9

equation for anaerobic respiration

Answer 9

glucose —> lactic acid

Question 10

how does lactic acid occur

Answer 10

when your body cant supply enough oxygen to your muscles during vigorous exercise therefore resorting to anaerobic respiration. this leads to oxygen debt as you need extra oxygen to break down the lactic acid to start aerobic respiration
