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 does enzymes catalyze reactions?

they reduce the activation energy required for the reaction to occur


What compounds catalyze metabolic reactions?

They are called enzymes; each one is specific for one metabolic reaction.


Without enzymes the metabolic pathways are?

Without enzymes, metabolic pathways would be extremely slow or unable to proceed because enzymes are needed to catalyze the chemical reactions that occur in these pathways. Enzymes lower the activation energy required for these reactions to take place, allowing them to occur efficiently within cells.


Do enzymes catalyze both forward and reverse reactions?

Yes, enzymes can catalyze both forward and reverse reactions by lowering the activation energy required for the reaction to occur in either direction.


What controls the chemical reactions in a cell?

Enzymes are responsible for controlling the chemical reactions in a cell. These protein molecules catalyze specific biochemical reactions by lowering the activation energy required for the reaction to occur, allowing cells to efficiently carry out various metabolic processes.


What chemical reduces the amount of activation energy needed for a reaction but is not a reactant?

Enzymes catalyze certain reactions.


Which part of the cell membrane can catalyze chemical reaction?

The part of the cell membrane that can catalyze chemical reactions is primarily composed of membrane proteins, specifically enzymes. These integral or peripheral proteins can facilitate biochemical reactions by acting as catalysts, lowering the activation energy required for the reaction to occur. Additionally, some membrane proteins are involved in signaling pathways, which can also influence metabolic processes.


What Organic molecules that catalyze reactions in living systems are?

Enzymes are the organic molecules that catalyze reactions in living systems. They act as biological catalysts by decreasing the activation energy required for a chemical reaction to occur. Enzymes are typically specific to particular substrates and can speed up reactions by many orders of magnitude.


What is the definition of enzyme?

Enzymes are proteins that are able to catalyze (i.e accelerate) biochemical reactions. During the course of a reaction, the enzyme is able to convert a substrate to a product but the enzyme does not get consumed in the reaction.


Why are enzymes so vital to life?

Enzymes are catalysts for the various chemical processes in the body. By lowering the activation energy of reactions, these enzymes catalyze the biochemical reactions necessary for life.


Proteins that catalyze reactions are called?

Enzymes. They are biological molecules that facilitate chemical reactions by lowering the activation energy required to convert substrates into products. Enzymes are highly specific, often catalyzing only one type of reaction.


How do enzymes catalyze reactions?

Enzymes catalyze reactions by lowering the activation energy required for the reaction to occur, making it easier and faster for the reaction to take place. This is achieved by binding to the substrate molecules and facilitating the formation of the transition state, which leads to the formation of the product.
