How can enzyme activity be regulated?
Enzymes are catalytic molecules that speed up the rates of reactions.(a) Explain why enzymes are necessary in biological systems.(b) Discuss three control mechanisms that regulate enzymatic activity.A) Enzymes decrease the amount of activation energy required for chemical reactions to occur.B) 1. Cofactors and Coenzymes- Inorganic ions and non protein organic molecules that are necessary to be present on the active site for some enzymes to work. These cofactors participate in the reaction and may even accept or contribute atoms to the reactions.2. Competitive and Noncompetitive inhibition- Limits the enzyme activity. This occurs when a molecule binds to an enzyme, either on the active site or allosteric site, and decreases its activity.3. Allosteric Regulation- Causes a different shape in the enzyme. May either inhibit or stimulate an enzymes activity.
What is a sentence for chemical energy?
Vegetables and fruits turn into chemical energy for your body.
Does a lamp have chemical energy?
when you turn on a lamp it is first light energy to chemical energy!
What is meant by biochemical reaction?
Chemical compounds consists of bonds of different chemical elements. For example, table salt is sodium chloride, which is a compound that consists of sodium atoms with chloride atoms, the strong-smelling chemical you find in bleach. A chemical element, on the other hand, is a chemical made of a single atom. The atom has a shell that contains positive and negative charges, electrons, and other partials depending on the chemical properties. Extremely unstable elements emit a type of energy called radiation, usually in the form of ionizing radiation, the type you find released by an nuclear weapon.
What is the chemical in which plants turn light energy from the sun into chemical energy or food called?
This chemical is chlorophyll.
Chemical mechanisms that can turn off or reduce an enzyme are what?
These chemicals are called competitive inhibitors.
What does a enzyme do in chemical reaction?
An enzyme generally lowers the activation energy necessary for a reaction to proceed. This in turn may cause more of the reactants to go to products.
What is aldolase?
Aldolase is an enzyme found throughout the body, particularly in muscles. Like all enzymes, it is needed to trigger specific chemical reactions. Aldolase helps muscle turn sugar into energy.
Can an enzyme be reused after catalyzing a chemical reaction?
Yes, enzymes can be reused over and over again for catalyzing chemical reactions because they are not consumed during the reaction, so they will remain in solution to quicken the reaction again with fresh substrates. Think of an enzyme as a container that forces its substrates to be in closer proximity to each other, which increases the chances of collisions and, in turn, the chances for a reaction to occur faster.
Does vmax increase with increasing amount of enzyme?
Yes, Vmax has a linear relationship with the amount of enzyme. This in turn deceases the Km of the reaction.
Can one enzymes be used for many different type of chemical reactions?
yes because it gets substrates that fit in and then when those product turn into more products the enzyme just moves on making more products
How do competitive inhibitors stop a chemical reaction?
Inhibitors decrease the rate of a reaction. However the use of inhibitors can be useful in decreasing the rates of unwanted side reactions. For instance if Chemical A could turn into chemical B or chemical C, but chemical C was useless, an inhibitor could be used to reduce the amount of C formed and maximise the amount of B produced from A. This is especially important in industrial processes, where undesired products waste reactant and thus money.
What does vitamins turn into when broken down by an enzyme?
Chuck Norris's Grandmother
Why do enzymes react?
The molecule that an enzyme react with, works on, is called a substrate. The substrate varies from one enzyme to another. The active site is the 3-D shape on the enzyme where a substrate binds for the reaction to take place.

Do lawnmowers turn electrical energy into chemical energy?
No, they turn chemical or electrical into kenetic energy
What substance is composed of amino acids?
Polypeptide, which will turn into an active protein or an enzyme.
