What else can I help you with?
What are the roles of enzymes?
Enzymes catalyze reactions by lowering the activation energy needed without themselves being used up in the process. Without catalysts such as enzymes, some chemical metabolic reactions would take forever to happen or not happen at all. a specific enzyme usually catalyzes only one kind of chemical reaction
What kind of chemicals react in a chemical reaction?
It solely depends on the reactions.
What kind of chemical change produces?
Exothermic reactions. E.g. combustion, oxidation
What chemical reactions in living things take place in what kind of solution?
Water
An enzyme is a special kind of catalyst that works to do what?
An enzyme is a special kind of catalyst that works to accelerate chemical reactions by lowering the activation energy required for the reaction to occur. This allows reactions to happen at a faster rate, making biological processes more efficient.
In chemical reactions The number of each kind of atom in the reactants?
Stays the same as in the products
How many different kinds of chemical reactions can one kind of enzyme control?
hundereds
In chemical reactions the number of each kind of atom in the reactants is?
It's the same as the product :)
What kind of chemical reactions speed up enzyme catalysis?
This varies per enzyme and what it catalyzes but chemical reactions that result in an increase in temperature often speed up enzyme catalysis.
What kind of potential energy is energy stored in foods and fuels?
This is chemical energy, since chemical reactions are required to release it
What kind of reactions does oxygen take part?
Oxygen can take part in a variety of reactions, such as combustion (burning), oxidation reactions, and reactions in biological processes like respiration. It is a highly reactive element that readily participates in chemical reactions.
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.
