Answer:

Enzymes are proteins that catalyze chemical reactions that occur in living things. They accelerate the speed of reactions, which contributes to metabolism. Without enzymes, many reactions would be extremely slow.

Explanation:

Each enzyme is specific to a type of reaction. That is, they only act on a given compound and always perform the same type of reaction. The compound on which the enzyme acts is generally referred to as substrate. The great enzyme-substrate specificity is related to the three-dimensional form of both.

The enzyme binds to a substrate molecule in a specific region called a binding site. For this, both the enzyme and the substrate undergo conformation change for the socket.

They fit perfectly like keys in locks. We call this behavior the Key-Lock Theory.

Answer:

Enzymes are proteins that allow certain chemical reactions to take place much quicker than the reactions would occur on their own.

Explanation:

Enzymes function as catalysts, which means that they speed up the rate at which metabolic processes and reactions occur in living organisms.

What are the five main phases of the cell cycle? What are the main events in each?
saveliy_v [14]

Answer:

In the adult organism, mitosis plays a role in cell replacement, wound healing and tumour formation. Mitosis, although a continuous process, is conventionally divided into five stages: prophase, prometaphase, metaphase, anaphase and telophase.

Cell cycle has different stages called G1, S, G2, and M. G1 is the stage where the cell is preparing to divide. To do this, it then moves into the S phase where the cell copies all the DNA.
