Respiration key words

Aerobic Respiration

• Reaction that releases energy from food

• Uses oxygen

• produces carbon dioxide and water

Anaerobic Respiration

• Reaction that releases energy from food without using oxygen

• Produces lactic acid in mammals

• Produces carbon dioxide and ethanol in yeast

ATP (adenosine tri phosphate)

• Chemicals present in all cells

• Acts as an energy ‘currency’

• Molecule made up my respiration and releases energy quickly

• Used up by any process that needs a supply of energy

Cellular Respiration

• process where food molecules are broken down and the the stored chemical energy is released

EPOC (excessive post exercise oxygen consumption)

• Difference between how much oxygen you would need if you gained all the energy by aerobic respiration and how much oxygen is actually available

• oxygen debt

Mitochondria

• Organelle that carries out aerobic respiration

• Releases energy for the cell

• Place where most of the cell’s ATP is made

Recovery time

• time taken for lactic acid to be removed

• time taken for breathing and heart rates to normal resting rates

Respirometer

equipment used to measure the rate of respiration

Yeast

unicellular fungus
