Actually, not all living organisms carry out aerobic respiration as seen in the equation above. Some living things like yeast, are anaerobic and carry out fermentation. There are bacteria that can also carry out fermentation in the absence of oxygen. Fermentation is a type of respiration that produces 2 ATP which provides enough energy for anaerobic organisms to live. As long as there is an energy source, such as a carbohydrate for example, fermentation can occur in these anaerobic organisms.

Photosynthesis

a) This occurs in plants, algae and in some bacteria. This happens in the chlorplast with the help of chlorophyll

b)  6CO2 + 6H2O light --> C6H12O6 + 6O2

This produces glucose and oxygen from CO2 and water.

c) Plants, algae and some bacteria

 

Cellular respiration

a) This happens in mitochondria of a cell

b) 6O2 + C6H12O6 --> 6CO2 +6H2O + energy

This is the opposite of photosyntheis. The energy which was stored in glucose are taken out for the use in cells
