How do enzymes speed up chemical reactions? enzymes a) lower the activation energy of chemical reactions. b) raise the temperature of the cell, speeding chemical reactions. c) store atp, allowing more energy to be used in chemical reactions. d) act as miniature 'transfer trucks', gathering materials for chemical reactions, and placing them together.

A) Lower the activation energy of chemical reactions.

Explanation:

Enzymes speed up chemical reactions by lower the activation energy of chemical reactions. The lower the activation energy of a reaction faster will be the rate. Activation energy is the minimum energy required to start a chemical reaction.

Enzymes initiates the chemical reactions by to reactant at the active site. Like all catalyst, enzymes work by lowering the activation energy of chemical reactions. Many enzymes change shapes when substrates bind.

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.
