Catalysts lower the activation energy of reactions, usually by providing an alternate reaction pathway, or mechanism that does not require so much energy. Having a lower activation energy means that less energy has to be transferred to each molecule in order for the reaction to progress.

What type of molecule is made from amino acids and acts as a biological catalyst?

Molecules that act as catalysts in biological systems are enzymes. Enzyme catalyze chemical reactions by lowering the activation energy.


What is a type of protein or RNA molecule that speeds up metabolic reactions in plants and animals without being permanently changed or destroyed?

Enzymes are biological catalysts that speed up metabolic reaction rates by lowering the reaction's activation energy. Proteins and RNA molecules can both function as enzymes.


Why does Glycolysis and the Kreb's cycle do not capture all of the energy in a glucose molecule?

i think Some energy is always lost as heat during chemical reactions


What type of a molecule are enzymes?

Enzymes are proteins, which are made from smaller sub-units called amino acids. The amino acid sequence for various proteins is coded for by the DNA, and the amino acids are put together, according to this sequence, by the ribosomes. Enzymes have an active site, which is a particular portion of the protein that is responsible for carrying out the reaction. There are lots of enzymes in cells. Some enzymes are only expressed in certain cells where they are needed - this is partly what makes cells differentiated from other cell types. For example, liver cells will need different enzymes to skin or brain cells in order to carry out their specialised functions.

How does enzymes speed up chemical reactions in your body?

Reactions in the body need a certain amount of energy, called activation energy. Most reactions don't take place because this activation energy is too high. The enzyme bonds to the molecule which diminguishes the activation energy, so the reaction can take place. These enzymes de-bond from the new formed molecule afterwards.


What is a protein molecule that acts as a biological catalyst to speed up chemical reactions by lowering the energy of activation?

The presence of catalysts, usually enzymes.

How do enzymes affect the rate of reaction?

Enzymes speed up a reaction but they are not changed by the reaction. They are a protein molecule that helps other organic molecules enter into chemical reactions with one another but is itself unaffected by these reactions. In other words, enzymes act as catalysts for organic biochemical reactions.


How do enzymes speed up chemical reactions?

Enzymes lower the activation energy of a chemical reaction.


How do enzymes speed up chemical?

Enzymes are biocatalysts that speed up the biochemical reactions by lowering the activation energy. It will not be consumed at the end so it can be reused for the next reaction. It binds to thte substrate molecule and aids the biochemical conversion to product without being consumed.


What type of organic molecule is tyrosine?

Tyrosine is an enzyme which helps bond with other bass like Cytosine or Guanine to help speed up catalyst reactions in the body. They speed them up by lowering the activation level. These are produced naturally in the body.


If one molecule has more energy than another does it have a higher activation energy?

The activation energy refers to a chemical reaction.

What type of main molecule are enzymes?

Enzymes are specialized proteins. And proteins are made up from amino acids.


Activation energy to break chemical bonds is provided by?

Activation energy to break chemical bonds is provided by ATP. ATP molecule will store energy and release it for various cell activities.


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.
