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 molecule acts as a catalyst in living things?
Enzymes are the organic molecules that act as biological catalysts.
Enzymes allow chemical reactions to occur .?
Enzymes are biological molecules that act as catalysts, speeding up chemical reactions by lowering the activation energy required for the reaction to occur. They are highly specific in the reactions they catalyze, interacting with specific substrates to facilitate the conversion of reactants into products. This specificity is due to the unique three-dimensional shape of the enzyme's active site, which fits the substrate molecule like a lock and key.
Relate the shape of an enzyme to its ability to help in a chemical reaction?
An enzyme's specific shape allows it to bind with a substrate molecule, forming an enzyme-substrate complex. This interaction positions the substrate in a way that promotes the chemical reaction to occur more quickly and efficiently by lowering the activation energy required. The unique shape of the enzyme's active site is crucial for catalyzing the reaction with high specificity.
How does enzymes catalyze a chemical reaction?
by lowering activation energy to increase the reactionEnzymes are biological catalysts, and can hence lower the activation energy barrier of the reaction that it catalyses. Enzymes do this in several ways:1) Enzymes can provide a suitable environment for the reaction to take place. The active site of a enzyme can be highly acidic (pH
What is an activation site?
An active or activation site is a small opening in an enzyme where substrate molecules are bound, and go through a chemical reaction. This reaction is caused by the collision a substrate that slots into the active site of the enzyme.
Large protein molecule that speeds up a chemical reaction?
An enzyme is a large protein molecule that functions to speed up chemical reactions by lowering the activation energy required for the reaction to occur. Enzymes are highly specific to the reactions they catalyze and can be reused multiple times.
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 type of main molecule are enzymes?
Enzymes are specialized proteins. And proteins are made up from amino acids.
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.
What molecule acts as a catalyst in living things?
Enzymes are the organic molecules that act as biological catalysts.
What substance acts like a carrier molecule that facilitate chemical reactions?
Enzymes act as carrier molecules that facilitate chemical reactions by lowering the activation energy required for reactions to occur. They bind to specific substrates and help to bring them together in the correct orientation and environment for the reaction to take place. This allows the reaction to proceed at a faster rate than it would without the enzyme.
Is a substrate an enzyme?
No, a substrate is the molecule that the enzyme acts upon to catalyze a reaction. Enzymes are proteins that function as biological catalysts, helping to speed up chemical reactions by lowering the activation energy.
How do enzymes speed up chemical reactions?
Enzymes lower the activation energy of a chemical reaction.
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?
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 is one function of a protein macro-molecule?
One function of a protein macro-molecule is to act as enzymes, which are biological catalysts that help facilitate chemical reactions in the body by lowering the activation energy needed for the reaction to occur.
What organic molecule can also function as a castalyst for chemical reactions?
Enzymes are organic molecules that can function as catalysts in chemical reactions. These biological catalysts, typically proteins, accelerate reactions by lowering the activation energy required for the reaction to occur. Enzymes are highly specific, meaning they usually catalyze only one type of reaction or act on a specific substrate. Their catalytic activity is essential for various biological processes, including metabolism and DNA replication.
