Topic 4:Bioenergetics 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+water
Anaerobic respiration
A form of respiration that releases energy from molecules
like glucose without using oxygen - represented by the following word equation: Glucoase—–>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
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.
