Explain how enzymes catalyst chemical reactions.

A fundamental task of proteins is to act as enzymes—catalysts that increase the rate of virtually all the chemical reactions within cells. Although RNAs are capable of catalyzing some reactions, most biological reactions are catalyzed by proteins.

Explanation:

In a chemical reaction, enzyme acts as catalyst. It accelerates the rate of reaction by lowering the activation energy needed to start a reaction. The enzyme converts substrate into product without changing itself.  Thus enzymes speed up reactions by lowering activation energy.

i think its control and coordinate because im pretty sure thats what tissue does and the joints are what control movement and then your skeletal/ bones provides portection. hope that .

the diploid number of chromosomes is sometimes represented by the symbol 2n. for the fruit fly, the diploid number is 8, which can be written as 2n = 8, where n represents twice the number of chromosomes in a sperm or egg cell.
