Why are enzymes needed to control chemical reactions with cells?

enzymes are needed to control chemical reactions within cells because the enzymes acts like catalysts. They basically speed up the reactions within the body, and within the cells, so there fore they help the body maintain its internal environment (homeostasis).

What chemical is absolutely needed for chemical reactions to happen in a cell?
These chemicals are called enzymes.
Which statement will be describe how enzymes effect chemical reactions?
Enzymes lower the activation energy needed to start a chemical reaction.
Is protein good for the body?
YES! Lean protein such as turkey, chicken, fish, filet mignon, are ESSENTIAL to the development and maintenance of muscle mass.
How do enzymes control the rate of reaction?
Not exactly. An enzyme is a form of catalyst. Organic in nature, they can be astonishingly powerful compared to the inorganic catalysts such as platinum, nickel or water. A catalyst generally speeds up a reaction. The control of reaction speeds in the body usually involves two enzymes, one a catalyst and the other an antagonist which interferes with the function of the first one. Some form of feedback loop finely adjusts the amounts of each of these, and the balance controls the speed of the reaction.
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.
Why are enzymes needed to control chemical reactions in cells?
it acts as a catalyst

What chemical reduces the amount of activation energy needed for a reaction but is not a reactant?
Enzymes catalyze certain reactions.
What are complex proteins that speed up chemical reactions by lowering the amount of energy needed to get the reaction started.?
enzymes
Why are enzymes necessary for anabolic reaction to occur in living organisms?
Enzymes allow many chemical reactions to occur. They catalyze reactions by lowering the activation energy, which is the amount of energy needed to trigger a chemical reaction. Whereas heat can provide energy to trigger reactions, temperatures needed to reach activation energy for most metabolic reactions are often too high to allow cells to survive, so enzymes are in fact needed if metabolism (anabolic or catabolic) is to occur.
