What do enzymes do inside living cells?
Enzymes are inside our cells in our body, they are meant there so we won't be sick and feel terrible, not only us but the cells protecting the enzymes are protecting us so we won't feel terrible, but it depends on how you help your body, the cells, and the enzymes.
Is the nucleus involved in chemical reactions?
No, the nucleus is not directly involved in chemical reactions. Its main role is to store and protect the genetic material of the cell. Chemical reactions primarily occur in the cytoplasm of the cell where enzymes and molecules interact.
Only small amounts of enzymes are required for reactions within cells because enzymes are?
Enzymes are catalysts that speed up chemical reactions by lowering the activation energy required for the reaction to occur. This means that only small amounts of enzymes are required to facilitate reactions in cells efficiently. Additionally, enzymes can be reused multiple times, further reducing the need for large quantities.
How do cells regulate synthesis to conserve energy?
Cells regulate synthesis by controlling the activation of enzymes involved in metabolic pathways. This is done through feedback inhibition, where the end product of a pathway inhibits the enzyme responsible for its synthesis. By regulating when and how much of a certain product is produced, cells can conserve energy by only making what is necessary for their immediate needs.
What is the job of an enzyme?
Enzymes are the protein molecules which are involved in the metabolic reactions in the body. These enzymes act as catalysts to various biochemical reactions that take place both in the cell and in extracellular fluids such as stomach acid. They leave the reaction as they entered it with no net chemical changes to the enzyme itself, although some enzymes will chemically react with substrates to form enzyme-substrate intermediates part way through a reaction. They accelerate the reaction by decreasing the activation energy of the reaction, and by weakly binding and orienating substrates into reaction favourable conditions. Enzymes can be called biocatalysts. Most enzymes are proteins but not all proteins are enzymes. There are also Ribozymes, which are enzymes but catalysis is by RNA rather than protein. The ribozyme was first observed by Zaug & Cech in 1986. For their work on ribozymes Thomas Cech and C. Altman received a Nobel prize in 1989. There are several different types of enzymes. Enzymes are highly specific, meaning a particular enzyme will only take part in the particular reaction that it was designed for. • Isomerases - involved in isomerization reactions • Ligases - used to join bonds [ATP is required] • Hydrolases - involved in the hydrolysis of bonds in the presence of water • Transferases - these type of enzymes are helpful to transfer one substrate to another. • Lyases - involved in non-hydrolytic cleavage of bonds •Oxidoreductases - involved in oxidation and reduction reactions This list is non-exhaustive - there are many other types of enzymes as well.

What statements is true about enzymes?
One thing that is true about enzymes is that enzymes speed up metabolic processes and are highly specific.
Proteins that catalyze reactions are called?
Enzymes. They are biological molecules that facilitate chemical reactions by lowering the activation energy required to convert substrates into products. Enzymes are highly specific, often catalyzing only one type of reaction.
Why enzymes are so particular about reactions?
Enzymes are complex molecules with intricate structure. It may help to think of them as being somewhat like keys: a key only opens the locks it fits, and enzymes only catalyze reactions where the molecule fits properly with the enzyme's active site.
Do chemical reactions result in the nuclei of the atoms involved?
No, chemical reactions result only in the electrons of the atoms being involved. Only radioactivity results n nuclei of atoms being involved.

Enzymes are catalysts. This means that they are able to speed up chemical reactions. Which of the following statements is also true of enzyme catalysts?
They occur more quickly than reactions without enzymes.They occur more quickly than reactions without enzymes.
What group of molecules are enzymes?
Most enzymes are proteins. 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.
How do enzymes affect reactions?
Enzymes speed up chemical reactions by lowering the activation energy required for the reaction to occur. They do this by binding to reactant molecules and bringing them together in the correct orientation to facilitate the reaction. Enzymes are specific to certain substrates, so they only catalyze specific reactions.
