Answer 1

Answer:

Catalysts accelerate chemical reactions. The molecules upon which enzymes may act are called substrates, and the enzyme converts the substrates into different molecules known as products. Almost all metabolic processes in the cell need enzyme catalysis in order to occur at rates fast enough to sustain life.

Answer 2

answer for first is

Catalyst is a common word that you might come across while studying chemistry especially while learning about chemical reactions. While some of the chemical reactions occur quickly, some take a long time and require extra materials or effort. This is where a catalyst comes in.

answer for second is

1.)The enzyme and the substrate are in the same area. Some situations have more than one substrate molecule that the enzyme will change.

2.)The enzyme grabs on to the substrate at a special area called the active site. ...

3.)A process called catalysis happens. ...

4.)The enzyme releases the product.
