Respiration and Photosynthesis - Aerobic and Anaerobic

Question 1

what is cellular respiration

Answer 1

cellular respiration is an exothermic reaction which is continuously occurring in living cells

Question 2

how much energy in transferred in respiration

Answer 2

the energy transferred supplies all the energy needed for living processes

Question 3

what two ways can respiration take place

Answer 3

aerobic (using oxygen) or anaerobically (without oxygen)

Question 4

why do organisms need energy

Answer 4

for chemical reactions to build larger molecules
movement
keeping warm

Question 5

what do
1) C6H12O6
2) CO2
3) H20
stand for

Answer 5

1) glucose
2) carbon dioxide
3) water

Question 6

what equation represents anaerobic respiration in muscles

Answer 6

Glucose -> Lactic Acid

Question 7

why does anaerobic respiration transfer less energy than aerobic respiration

Answer 7

in anaerobic respiration the oxidation of glucose is incomplete

Question 8

what equation represents anaerobic respiration in plant and yeast cells

Answer 8

glucose –> ethanol + carbon dioxide

Question 9

what is the name for anaerobic respiration in yeast cells and why is it important

Answer 9

fermentation and has economic importance in the manufacture of bread and alcoholic drinks
