Which statement describes how enzymes and substrates are related? the enzyme influences the speed of change from substrate to product. enzymes are released as substrates in a chemical reaction. an enzyme is a special kind of substrate in a chemical reaction. substrates combine with enzymes to form reactants.

Correct A). The enzyme influences the speed of change from substrate to product

The enzymes are the biological catalyst that speed up the rate of chemical reactions by decreasing the activation energy of the reaction pathway.

They increase the speed of change of substrate to the product and it remains unchanged in the reaction. Hence, it can be used again and again.

Enzymes are highly specific in nature, only a specific substrate binds to the enzyme's active site. Hence, a particular enzyme is required to catalyze a reaction.

the cladogram shown here shows similarities and differences among several classes of vertebrates. anatomically, the four have limb structure as their common ancestor. we might separate the mammals from the other three classes because they a) divergent; do not lay eggs b) identical; are warm-blooded c) varied; a four chambered heart d) homologous; have mammary glands
