Many factors can influence the rates of reaction

Enzymes or Catalysts can reduce the activation energy for a reaction, speeding it up hundreds or thousands of times the "normal rate"

Temperature

The physical amount of the two things reacting

Enzymes are proteins that catalyze chemical reactions

Although the enzymes themselves are incapable of regulating these reactions, the enzymes are self-regulated through mechanisms like feedback inhibition and competitive inhibition. Therefore, enzymes indirectly regulate the biochemical reactions which they catalyze

Enzymes catalyze all chemical reactions in cells. The reaction rate of an enzyme can change depending on the temperature, pH level, ionic concentration and other factors. A cell can also control the reaction rate through competitive and non-competitive inhibitors, which can denature the enzyme causing the substrate to not be able to fit into the enzyme's active site.

By nature if you have healthy cells they will automatically split on their own. The rates of splitting does not vary. The only time someones splitting would be lesser or greater than a normal person is if they suffered from a disorder such as Sickle Cell Anemia.

Enzymes catalyze all chemical reactions in cells. The mitochondria is the control rate of metabolism by releasing enzymes that can either speed it up or can slow it down.

Temperature is probably the biggest factor.

But

  • Catalysts
  • Grain size (surface area of reaction surface)
  • Light
can also modify a reaction rate.

What is the rate of chemical reaction is?

The rate of chemical reactions is how long a chemical reaction takes to finish.


What controls the rate of chemical reaction in human body?

In the human body enzymes control the rates of chemical reactions. Enzymes speed up reactions by lowering the activation energy, or the amount of energy required for the reaction to occur.


What controls the rate of chemical reactions in cytoplasm?

mitochondria


How does increasing the temperature effect a chemical reaction?

Raising the temperature makes chemical reactions faster.


Chemical reactions are at what when a reaction and its reverse happen at an equal rate?

Equillibrium


Catalysts are that increase the rate of a chemical reaction?

Why are catalysts reaction specific Iethey are different for different chemical reactions How catalyst modifies the rate of a chemical reaction Why don't they take part react in the chemical reaction?

Catalysis reaction are the generic potential energy. Chemical reactions is the process that leads to the transformation of a set chemical.


Which best describes the role of enzymes in chemical reactions?

to increase the reaction rate


What does it mean if enzymes are organic catalyst?

Enzymes are organic catalysts. A catalyst is a chemical that controls the rate of a reaction, but is itself not used up in the process. Reactions that are accelerated due to the presence of enzymes are known as enzyme-catalyzed reactions.


How does increasing pressure affect the reaction rate?

The concentration of reactants is changed.


What is the relationship between the temperature and the rate of chemical?

Heat energy is necessary for some chemical reactions to occur. Some chemical reactions are endothermic meaning they require or absorb energy for a chemical reaction to occur. Other chemical reaction are exothermic meaning they release energy when the chemical reaction takes place..


What is a material that slows down the rate of a chemical re action?

In general, a material that decreases the rate of a chemical reaction is called an inhibitor.
