Sexual reproduction is associated with Meiosis. In this form of cell division, the number of chromosomes in the parent cells are reduced by half. The cells after division are called haploids. This mechanism is needed to make egg and sperm cells for sexual reproduction.
Enzymes are biological molecules (typically proteins) that significantly speed up the rate of virtually all of the chemical reactions that take place within cells. Enzymes are highly selective catalysts, meaning that each enzyme only speeds up a specific reaction. Hope I’ve helped ;)
