Enzymes are important in cell's chemical reaction. Describe what a enzyme's role in chemical reactions is and explain what an en
zyme does. The following key words may help you structure your response: active site, enzyme-substrate complex, and activation energy. Please try to use...
Enzymes are proteins that catalyze chemical reactions that occur in living things. They accelerate the speed of reactions, which contributes to metabolism. Without enzymes, many reactions would be extremely slow.
Explanation:
Each enzyme is specific to a type of reaction. That is, they only act on a given compound and always perform the same type of reaction. The compound on which the enzyme acts is generally referred to as substrate. The great enzyme-substrate specificity is related to the three-dimensional form of both.
The enzyme binds to a substrate molecule in a specific region called a binding site. For this, both the enzyme and the substrate undergo conformation change for the socket.
They fit perfectly like keys in locks. We call this behavior the Key-Lock Theory.
The increase in muscle tension that is produced by increasing the number of active motor units is called. recruitment. The type of contraction in which the muscle fibers do not shorten is called. isometric.
The ventricular systole occurs when pressure rises in the ventricles causing that blood pumps from the right ventricle and into the aorta from the left ventricle. The beginning of this step is given when blood flowing back towards the atria, closing the tricuspid and mitral valves. It is false that the blood flows back towards the relaxed ventricles as it is stated in the question.
