Enzymes are biological catalysts - catalysts are substances that increase the rate of chemical reactions without being used up. Enzymes are also proteins and thus have a specific shape. They are therefore specific in the reactions that they catalyse - one enzyme will react with molecules

Light and nutrients. Light is the key abiotic factor which controls the growth of woodland. It controls the spacing of the trees‚ shape of the trees and the shape and structure of the shrub and ground layers. If a trees branch does not receive enough light it will die.

different sugar types affects rate of respiration. The experiment showed that the yeast produces the highest volume of CO2 with glucose. It also showed the yeast respires at its lowest rate with sorbose and maltose was in between the rate of yeast respiration of glucose and maltose. Introduction In this investigation we are going to investigate the amount of respiration by how much carbon dioxide is produced‚ and how using sorbose‚ glucose and maltose sugar types affects rate of respiration.
