respiration endo/exothermic

Question 1

what type of reaciton is respiration

Answer 1

exothermic because it releases energy

Question 2

what is the word equation for aerobic respiration

Answer 2

glucose + oxygen ——–carbon dioxide + water
-
-
-energy

Question 3

what does aerobic respiration do and explain why

Answer 3

releases a great amount of energy because of the glucose molecules have been fully oxidized

Question 4

what are the chemical symbols of aerobic respiration

Answer 4

C6.H12.O6 + O2 ——- co2 + H2O

Question 5

what do cells need to carry out respiration

Answer 5

oxygen

Question 6

how does anaerobic respiration in work in muscle cells

Answer 6

when there is a shortage of oxygen muscle cells respire anaerobically

Question 7

what is the word equation of anaerobic respiration in muscles

Answer 7

glucose——- lactic acid
-
-
- energy

Question 8

what does anaerobic respiration not require and how does i affect the amount of energy you get from it

Answer 8

oxygen

anaerobic respiration releases much less energy than aerobic respiration because the oxidation of glucose is not complete

Question 9

show anaerobic respiration in pant and yeast cells

Answer 9

glucose ———– ethonal + carbon dioxide
-
-
-energy

Question 10

how can anaerobic respiration be useful in yeast cells and what is it called

Answer 10

fermentation which we use to react to make alcoholic drinks e.g beer

Question 11

how can fermentation be useful when making bread

Answer 11

carbon dioxide produced by fermentation is useful as it can make bubbles in the dough causing the bread to rise
