Biology help...yay...so much fun XD lol?

Question

Glycolysis occurs during the second step of cellular respiration.

True

False

Pyruvate produced during glycolysis enters the mitochondria during the second step of cellular respiration.

True

False

Fermentation and aerobic respiration both take place in the absence of oxygen.

True

False

Cellular respiration produces more ATP than fermentation.

True

False

Anaerobic exercise burns more calories than aerobic exercise.

True

False

A calorie is the amount of energy it takes to raise your body’s temperature.

True

False

In both plants and animals, food molecules are broken down and CO2 is released by

1. respiration.

2. the carbon cycle.

3. breathing.

4. glycolysis.

Answer 1

1. False, glycolysis is the first step in carbohydrate catabolism.

2. True, Glycolysis occurs in the cytosol after which the product (pyruvate) enters into the matrix of the mitochondrion.

3. False, aerobic is always referring to the presence of oxygen.

4. True, cellular respiration creates 38 ATP compared to 4 ATP of fermentation from one molecule of glucose.

5. False, but I can't give you an explanation because this question is horribly written.

6. False, a calorie is the amount of energy required to raise the temperature of 1 kg of water by 1 degree Celcius

7. respiration
