1

What is cellular respiration?

An exothermic reaction which is continuously occurring in living cells. The energy transferred supplies all the energy for living processes.

2

Compare the processes of aerobic and anaerobic respiration.

Aerobic needs oxygen to work.
Aerobic produces CO2 + water, anaerobic produces lactic acid.
Aerobic respiration produces much more energy per glucose molecule than anaerobic respiration.
Both need glucose.

3

What do organisms need energy for?

Chemical reactions to build larger molecules.
Movement
Keeping warm

4

What is the equation for aerobic respiration?

glucose + oxygen = carbon dioxide + water
C6 H12 O6 + O2 = CO2 + H2O

5

What is the equation for anaerobic respiration in muscles?

glucose = lactic acid

6

What is the equation for anaerobic respiration in plant and yeast cells?

glucose = ethanol + carbon dioxide

7

How is anaerobic respiration used in yeast cells?

Happens in microorganisms as they need to release energy too. This type of respiration is called fermentation and produces ethanol + CO2, ethanol is useful for brewers and winemakers and CO2 helps make bread rise.
