Metabolic reactions require organic catalysts called?
Metabolic reactions require organic catalysts called enzymes. These enzymes lower the activation energy of the reaction, thus increasing its reaction rate.
Is enzymes provide energy for specific chemical reactions in cells true?
ATP supplies its energy by breaking its gamma pyrophophate bond and releasing the terminal phosphate. This phosphate is attached onto a substrate where it affects the reactivity of the substrate, leading to reaction. Therefore ATP is only used in enzymes that catalyze phosphorylation reactions to drive reactions. Though this is a very large group of enzymes, there are enzymes that do not require ATP or require energy from other sources (H+, ADP, NADH, etc.). It is useful to realize that "energy" is not an intangible thing in a cell, rather it is associated with particular ions and functional groups that alter the reactivity of substances to drive reactions.
Do anabolic pathways depend on enzymes?
Yes. They require an input of energy (endergonic) as they form bonds between molecules, e.g. building polymers.
The processes of endocytosis and exocytosis both require what?
Endocytosis is accomplished by the release of hydrolytic enzymes from lysosomesExocytosis and endocytosis are accomplished by the energy from ATP. These are the processes that are respectively responsible for removing materials from and into the cell.Plasma Membrane
Describe how enzymes catalyze metabolic reactions by lowering activation energy?
Enzymes lower activation energy because they have energy. Enzymes help to speed up reactions or start reactions by using their own internal energy to do so.
Metabolic reactions require organic catalysts called?
Metabolic reactions require organic catalysts called enzymes. These enzymes lower the activation energy of the reaction, thus increasing its reaction rate.
What does cells require in order for chemical reactions to take place?
enzymes
What technology is needed with solar energy?
Electrical, electronic, thermal and mechanical, all of which require mathematics.

Why are enzymes important to human health?
Chemical reactions have several different energy levels. They have an energy level for the products, the reactants, and an intermediate. The difference in energy between the intermediate and the ractants is called the activation energy. Enzymes reduce the activation energy of reactions and therefore allow reactions to occur within the human body. Reactions require three things: collision, collision with sufficient energy, and collision in the correct orientation. Enzymes increase the collision probability by holding the reactants in place. They also decrease the activation energy. Enzymes also orient the reactants in the correct orientation because of its specific binding sites.

Enzymes lower activation energy because they have energy. Enzymes help to speed up reactions or start reactions by using their own internal energy to do so.
How do enzymes work what do they lower?
Enzymes function when they lower the activation energy. That means it takes less energy for the reaction to work.
What kind of energy do enzymes reduce?
activation energy activation energy
What allows cells to produce energy through aerobic metabolism?
The chemical reactions of metabolism are organized into metabolic pathways, in which one chemical is transformed through a series of steps into another chemical, by a sequence of enzymes. Enzymes are crucial to metabolism because they allow organisms to drive desirable reactions that require energy and will not occur by themselves, by coupling them to spontaneous reactions that release energy.
Which statement best explains how enzymes speed up chemical reactions?
Enzymes lower the activation energy of a chemical reaction.
