A catalyst is a chemical species that alters the rate of a chemical reaction without undergoing any type of change. Such catalysts that slow down a reaction are called negative catalysts or poison.

What is the role of enzymes as catalysts of living tissues?
It speeds up the rate of reactions in the body.
What is an enzyme's role in chemical reactions?
Enzymes are proteins found in living things that act to catalyze specific reactions. Made up of a complex of amino acids, enzymes are part of every chemical reaction in living things. They aid in digestion, the growth and building of cells, and all reactions involving the transformation of energy. Inside the cell, enzymes create RNA and DNA by facilitating the reaction of ribose with adenosine. They also specify the sites for linking to build RNA along a DNA template.
What describes the role of sunlight in chemical reactions?
it provides energy for some reactions to take place.
What is the major role of proteins in the body?
To function as enzymes (in chemical reactions).
What is the role of enzymes in chemical reactions within the cell?
The are catalysts. They make it a LOT easier and more likely for some otherwise pretty improbably reactions to occur. Like all catalysts they aren't consumed by reactions they catalyse. But also present in the cells are many proteases. They breakdown proteins, including enzymes, and recycle the ingredients used to make them. And enzymes are continuously being produced, the amounts of which depend on what genes are expressed at the moment, all controlled by hundreds of hormones and other chemical signals with in and from outside the cell. So in this way the function of the cell can change in response to external cues and internal conditions.
How chemicals play an important role in the physiological aspect of the body?
Enzyematic reactions that occur from chemical reactions in the body speed up the activity and physiologically have everything to do with chemical reactions in the body.
What is the role of enzymes as catalysts of living tissues?
It speeds up the rate of reactions in the body.
Describe the role that enzymes play in the process of metabolism?
Enzymes increase the rate of the chemical reactions carried out during metabolism.
Describe the role of energy in chemical reactions?
Chemical reactions that release energy often occur spontaneously. Chemical reactions that absorb energy will not occur without energy.
What is the role of oxygen in chemical reactions?
it makes you breathe

What are The subatomic particles that play the greatest role in cellular chemical reactions?
the particulat part is the electrons. They can from ionic bonds or covalant bonds. They constantly change the chemical properties of the atoms.
Do All the subatomic particles participate in chemical reactions?
Usually, only electrons participate in chemical reations. The other subatomic particles play a larger role in nuclear chemistry.
What describes the role of sunlight in chemical reactions?
it provides energy for some reactions to take place.
What is the role of energy in chemical reactions?
energy is released or absorbed.
What are enzymes What is their role in a cell?
Enzymes speed up chemical reactions.
What is the major role of proteins in the body?
