(ii)Catabolism (also Katabolism) - Break down of complex molecules into simpler molecules to release energy, i. e. breaking down of hydrocarbons into the simpler forms with the release of energy. These current convert ADP (adenosine diphosphate) into ATP (adenosine triphosphate) and split water molecules in the cells into oxygen and hydrogen-paving the way for the whole complex process of photosynthesis. The energy released in such reactions is stored and used for growth and development....

Proceedings of the Royal Society of London, Biological sciences In such gametes the «centrosomes become more or less definitely related to the flagella, just as the extra-nuclear ceutrosome is related to the flagella of the trypanosomes. In many metazoan gametes (reptiles) the flagellum abuts ... |
