Answer 3

as chemical energy and heat

Question 4

to do things like create large molecules from smaller ones (e.g. proteins from amino acids) and contract musecles

Question 5

what is heat energy released in repsiration used for

Answer 5

helps maintan a steady body temp

aerobic word eq

Answer 6

glucose + oxygen —-> carbon dioxide + water

Question 7

aerobic symbol eq

Answer 7

C6H1206 + 602 ——-> 6C02 + 6H20

Question 8

anaerobic respiration word eq (in animals)

Answer 8

glucose —–> lactic acid (+energy)

Question 9

anerobic respiration word eq (in plants/fungi)

Answer 9

glucose —–> ethanol + carbon dioxide (+ energy)

Question 10

aerobic respiration info

Answer 10

1) occurs when there is plenty of oxygen avalibale
2) most effieicnt way to release energy from glucose
3) most frequent type of respiration

Question 11

anaerobic respiration info

Answer 11

1) when you do vigrorous excersize, your body can’t supply enough oxygen to your muscles for aerobic respiration- even though your heart rate and breathing rate increase as much as they can, your muscles have to start respiring anaerobically as well
2) It is not the best way to convert glucose into energy because it releases much less energy than aerobic respiration, glucose is only partially broken down and lactic acid is produced
3) the lactic acid builds up in ,uscles- it gets painful and leds to cramp
