The first law of thermodynamics states that -

b. energy can neither be created nor destroyed, but it can change from one form to another.

Answer;
-supporting reactions involving energy transfer
Explanation;
-Enzymes are biological molecules (typically proteins) that significantly speed up the rate of virtually all of the chemical reactions that take place within cells.They are molecules made of amino acids that speed up chemical reactions by lowering the activation energy.
-The basic function of an enzyme is to increase the rate of a reaction. Most cellular reactions occur about a million times faster than they would in the absence of an enzyme. Second, most enzymes act specifically with only one reactant to produce products.
The answer is The personal items should be off the table and the lab materials should be placed neatly away from the edge of the table.
As a general rule, personal items and lab items should not mix, especially food items like a lunch bag. Certain lab materials can be dangerous if touched or handled without the proper protective gear. By placing personal items so close, you are increasing the risk of accidents, which is also why lab materials should be away from the edge of the table.
