What functions do allosteric enzymes serve in reaction sequences?
Enzyme reaction rates can be decreased by various types of enzyme inhibitors. ... Enzymes serve a wide variety of functions inside living organisms
Enzymes speed up chemical reactions by?
by lowering the activation energy of reactions
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.
The effect of substrate concentration on the rate of reaction of h202 and catalase?
As the substrate concentration increases, so will the enzyme activity and hence there will be a quick reaction. however, only up to a certain point ( where, if you drew a graph of the reaction, the line will level off ) as all the active sites in the enzyme are occupied and the reaction cannot go any faster. Here more enzymes will be needed to speed up the reaction.
What factors increase the rates of enzyme-controlled reactions?
** TEMPERATURE ** pH LEVEL ** PARTICLE SIZE ** SUBSTRATE CONCENTRATION
What affect rates does a enzyme catalyzed reaction have?
Enzymes increase the rate of reaction by changing the reaction mechanism to one with a lower activation energy.

Enzymes speed up chemical reactions by?
by lowering the activation energy of reactions
Is an enzyme a source of energy for endergonic reactions?
an enzyme is a protein that catalyzes (increases the rates of) reactions by lowering the activation energy required for the reaction. enzymes catalyze all kinds of reactions, including endergonic reactions.
Does tight binding between enzyme and its substrate imply rapid catalysis?
All catalysts, enzyme work via the lowering of the activation energy for a reaction this causes the rate of the reaction to increase dramatically. Should be noted that most enzyme with tight binding reactions rates are millions of times faster than those of of catalyst similar reactions. causing rapid catalysis
What will not affect reaction rates?
Astrological signs will not affect reaction rates.
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.
How does physical states relate to reaction rates?
The reaction rates are higher in gases.
The effect of substrate concentration on the rate of reaction of h202 and catalase?

Here more enzymes will be needed to speed up the reaction.
How does a enzyme increase the rates of reactions?
An enzyme increases the rate of the reaction by lowering the activation energy needed for the reaction. The secret is that enzymes weaken the bonds in the substrate so that products are formed much faster. Enzymes are catalysts or substances that speed up the reaction (without being consumed in it). An enzyme increases the rate of reaction by lowering the energy of activation or (Ea). Enzymes achieve that by attaching to the substrate in the active site and forming an enzyme substrate complex in which the enzyme disturbs the covalent bond of the substrate. This causes it to enter the transitional state, which is the most energetic and unstable state. The enzyme then breaks apart, and the substrate goes into an exorganic reaction to form the product.
What effects does temperature have on reaction rate?
An increase in temperature speeds up the reaction rate.
How nuclear decay rates different from chemical reaction rates?
nuclear decay rates take more time and chemical reaction rates could happen fast.
