What can be said of a relationship between the use of an enzyme and the energy of the reaction?
More energy is absorbed by reactions without an enzyme.
What happens when activation energy is in presence of an enzyme?
the energy decreases
What is the model of enzyme activity?
In a model of enzyme action, the enzyme can attach only to a substrate (reactant) with a specific shape. The enzyme then changes and reduces the activation energy of the reaction so reactants can become products. The enzyme is unchanged and is available to be used again.
Why is it important that an enzyme is stabilised?
it is important that an enzyme is stabilized because... a) the enzyme reduces the energy required to reach the highest energy of the reaction b) therefore the reduction of activation energy increases the number of reactant molecules with enough energy to reach the activation energy and form the product. c) the enzymes can collide faster with the substrate (also known as lock and key)
Chains of enzyme reactions in a Cell that regulate enzyme activity and energy flow are known as?
They are termed to be metabolic pathways.

Function of a enzyme?
An enzyme speeds up a chemical reaction by lowering the activation energy.
Give two forms in which energy is supplied by enzyme?
There is NO form of energy in which it can ever be supplied by enzyme, because enzymes do not change (chemically) in their supported reactions, and so 'energy' is never 'supplied' by any enzyme. It can however lower the activation energy but that is only a virtual form of chemical energy which cannot be added or lowered by anything.
What is the enzyme that acts as a motor - generating the energy currency of the cell?
ATP is the enzyme that acts as the motor for the cell. ATP generates the energy currency of the cell.
What is the model of enzyme activity?
In a model of enzyme action, the enzyme can attach only to a substrate (reactant) with a specific shape. The enzyme then changes and reduces the activation energy of the reaction so reactants can become products. The enzyme is unchanged and is available to be used again.
What is an enzyme complex substrate?
An enzyme-substrate complex uses the reactants(substrates) and the enzyme. The enzyme is like a catalyst that reduces the required activation energy and speeds up the chemical reaction.
What would an enzyme do in a cell?
it lowers activation energy.
What produces the energy in the enzyme in skeletal muscle?
Ndnnd

What is the main thing an enzyme does to catalyze a reaction?
The main thing that an enzyme does to catalyze a reaction, is to lower the energy of reaction.
