Topic 4 Bioenergetics - Definitions Flashcards
Aerobic respiration
A form of respiration that uses oxygen to release energy from molecules like glucose - represented by the following word equation
Glucose + Oxygen —> Carbon dioxide and Water
Anaerobic respiration
A form of respiration that releases energy from molecules like glucose without using oxygen - represented by the following word equation
Glucose —> Lactic Acid
Cellular respiration
An exothermic reaction which is continuously occurring in living cells.
Inverse proportion
A relationship between two values where as one value increases, the other value decreases at the same rate.
Inverse square law
As the distance from a light source increases, the light intensity is inversely proportional to the distance squared - given by the following equation
Light Intensity proportional to
1 / (Distance from light source) ^ 2
Limiting factor
A factor that limits the rate of a reaction when there is not enough of it.
Metabolism
The sum of all the reactions in a cell or the body.
Oxygen debt
The amount of extra oxygen the body needs after exercise to react with the accumulated lactic acid and remove it from the cells
Photosynthesis
An endothermic reaction in which energy is transferred from the environment to the chloroplasts by light.
