All cells of an organism are engaged in many different chemical reactions This fact is best supported by the presence in each cell of thousands of different kinds of?
enzymes
Why are there so many different enzymes?
because enzymes are just many different proteins put together so they can make many different combinations of enzymes.
A substance that causes or that speeds up a chemical reaction while the substance itself remains unchanged?
catalyst
Why are proteins so important to cells?
Thye have different functions. Some are antibodies which protect the body from foreign invaders. Some help with movement. Some are enzymes which help chemical reactions go quicker and smoother. Some help move molecules. There are many more functions but here are a few. Hope this helps!
What is the purpose of having enzymes within a cell?
Enzymes are biomolecules that catalyze (i.e., increase the rates of) chemical reactions. Almost all enzymes are proteins. In enzymatic reactions, the molecules at the beginning of the process are called substrates, and the enzyme converts them into different molecules, the products. Almost all processes in a biological cell need enzymes to occur at significant rates. Since enzymes are selective for their substrates and speed up only a few reactions from among many possibilities, the set of enzymes made in a cell determines which metabolic pathways occur in that cell.
Do One enzymes can be used for many different types of chemical reactions is this true or false?
True
What nutrient acts as a helper in many different chemical reactions in the body?
Vitamins. They are known as co-enzymes.
Why is it advantageous for the human body to have many different enzymes?
Each enzymes had a specific job. Meaning one kind could not do what others can. Meaning having many enzymes would be advantageous (or neccessry) for our body to do many kinds of chemical reactions.

Vitamins. They are known as co-enzymes.
How do enzymes affect reactions in living cells?
Enzymes are biological molecules that catalyze (i.e., increase the rates of) chemical reactions. In enzymatic reactions, the molecules at the beginning of the process, called substrates, are converted into different molecules, called products. Almost all chemical reactions in a biological cell need enzymes in order to occur at rates sufficient for life. Since enzymes are selective for their substrates and speed up only a few reactions from among many possibilities, the set of enzymes made in a cell determines which metabolic pathways occur in that cell. Enzymes are known to catalyze about 4,000 biochemical reactions.
Why are enzymes important in cell?
Enzymes speed up chemical reactions in a cell. without enzymes, many chemical reactions that are neccassarry for life would either take to long or not occur at all.

How many types of enzymes and metabolic-catalyzed reactions does a cell have?
9
What is a Protein that speeds up chemical reactions in living things?
Enzymes are a type of protein that catalyse chemical reactions. There are many different types. They speed up the reaction by lowering the activation energy. This is the amount of energy needed to begin the reaction. The proteins that are vital to living things because they speed up chemical reactions are called enzymes. They are catalysts that lower the activation energy of chemical reactions.
What proteins are vital living things because of they speed up chemical reactions by up to a trillion times?
You are thinking of enzymes a protein molecule that helps other organic molecules enter into chemical reactions with one another but is itself unaffected by these reactions. In other words, enzymes act as catalysts (speed up 1000x) organic biochemical reactions.
