Bioenergetics

Question 1

Aerobic Respiration

Answer 1

A form of respiration that uses oxygen to release energy from molecules like glucose.

Glucose + Oxygen –> Carbon dioxide + Water

Question 2

Anaerobic Respiration

Answer 2

A form of respiration that releases energy from molecules like glucose without using oxygen.

Glucose –> Lactic Acid

Question 3

Cellular Respiration

Answer 3

An exothermic reaction which is continuously occurring in living cells.

Question 4

Inverse Proportion

Answer 4

A relationship between two values where as one value increases, the other value decreases at the same rate.

Question 5

Inverse Square Law

Answer 5

As distance from a light source increases, the light intensity is inversely proportional to the distance squared.

Light Intensity = 1/ (Distance from Light Squared)

Question 6

Limiting Factor

Answer 6

A factor that limits the rate of a reaction when there is not enough of it.

Question 7

Metabolism

Answer 7

The sum of all the reactions in a cell or the body.

Question 8

Oxygen Debt

Answer 8

The amount of extra oxygen the body needs after exercise to react with the accumulated lactic acid and remove it from the cells.

Question 9

Photosynthesis

Answer 9

An endothermic reaction in which energy is transferred from the environment to the chloroplasts by light.
