They catalyze a reaction, making it operate at several orders of magnitude faster than it would otherwise, and don't change the end products
Think of it this way, if someone were to perform surgery sure they could probably do it alone... but things go much faster if there's an assistant (enzyme) there handing them the stuff they need
Some activities that cell requires energy may include cell division, active transport, protein synthesis etc.
In human, Cells get their energy by the food we eat. The nutrients in the food breaks down into soluble and simple molecules in stomach and small intestine and it is absorbed through the small intestine and assimilated into the cells, becoming part of it, providing the uses for each type of nutrient. And of course, many of them is the energy source.
New matter is not created because matter can neither be created nor destroyed (or so is said) where the matter comes from is from the matter it takes in such as sunlight, nutrients, water, and carbon dioxide, hope i helped.
This phenomenon is referred to as receptor situations.
Answer:
Repolarization
Explanation:
Repolarization refers to the phase during which the resting potential is restored after depolarization. This means that the inside of the axon membrane becomes negative again compared to the outside.
Repolarization is obtained by the functioning of K+ ion channels. The opening of K+ ion channels allows the K+ to move outside of the axon. Movement of positively charged ion (K+) outside of axon makes the inside negative again and the resting potential is restored.
