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... Continue Reading →
Light-Dependent Reaction – Photosynthesis Ep 1
Photosynthesis is the process used by plants and other photosynthetic organisms to produce glucose. The glucose can then go on to be used in respiration, stored as starch, or used for other purposes. Photosynthesis requires light energy, but it is actually only the first stage which is directly light-dependent. We will focus on the light-dependent... Continue Reading →
Coenzymes and Cofactors – Enzymes Ep 4
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... Continue Reading →
