During cellular respiration, carbon dioxide is produced. carbon dioxide is taken in by plants during photosynthesis to make food hence removing carbon dioxide from the atmosphere. These two processes make up the carbon cycle which maintains the concentration of carbon dioxide in the atmosphere.
<span>Enzymes are biological catalysts (they are proteins). Enzymes regulate metabolic pathways in the body.
e.g. Digestive enzymes in your stomach speed up the hydrolysis and breakdown of carbohydrates, proteins and fats in the food you consume.</span>
When glucose is high, cAMP is low; CAP does not bind the lac operator, and RNA polymerase does not bind the lac promoter. CAP is only active when glucose levels are low, which means the cAMP levels are high, and therefore the lac operon can only be transcribed at high rate when glucose is absent. The importance of this is that the bacteria only turns on the lac operon and start using lactose only after they have used up all the preferred energy source which is glucose.
