Light-Independent Reaction – Photosynthesis Ep 2

Diagram showing the Calvin cycle, also called the light independent reaction of photosynthesis.

In the last article we left photosynthesis at a point where ATP, reduced NADP, and oxygen had been produced in the light-dependent reaction. Oxygen is a waste product of photosynthesis, however the ATP and reduced NADP are used for the light-independent reaction. So although light energy isn't specifically needed for any reaction in this next … Read more

Light-Dependent Reaction – Photosynthesis Ep 1

Diagram of non-cyclic photophosphorylation. Part of the light-dependent reaction during photosynthesis.

Photosynthesis is the process used by plants and other photosynthetic organisms to make their own glucose. The glucose can then go on to be used in respiration, stored as starch, or used in other reactions. Photosynthesis requires light energy, but it is actually only the first stage which is light-dependent. We will focus on the … Read more

Coenzymes and Cofactors – Enzymes Ep 4

Diagram showing how coenzymes are changed and recycled.

So far in this series we have looked at how enzymes work, what can affect the rate at which they work, and how their action can be inhibited. Today we are looking at coenzymes and cofactors: non-proteins that are needed in order for some enzymes to be able to catalyse their reaction. Coenzymes Coenzymes are … Read more
