Coenzymes
Coenzymes are small organic molecules that, themselves, do not function as catalysts (i.e. enzymes) but aid the latter in carrying out their functions. Enzymes are biological catalysts, which means that they allow reactions to occur at lower activation energies. In a way, enzymes help to "speed up" chemical reactions.
Coenzymes are mostly derived from vitamins. Examples include TPP from Vitamin B1 (thiamine), FAD from Vitamin B2 (Riboflavin), and NAD+ from Niacin.
Answer:
<em>The correct option is C) It does not depend on insect pollination.</em>
Explanation:
Angiosperms can simply be described as the plants which produce flowers whereas gymnosperms are the plants which do not produce flowers.
Both, the gymnosperms and the angiosperms, are capable of producing seeds. However, the seeds of the angiosperms are enclosed in an ovary. The seeds of gymnosperms are not enclosed.
<u><em>One of the major differences between gymnosperms and angiosperms is that the angiosperms have to depend on animals for pollination. On the other hand, the seeds of gymnosperms are spread through the wind and are pollinated.</em></u>
