A lot of homework questions, today. I wouldn't answer but the questions are always written poorly due to teachers not understanding their subject matter.
Your teacher probably wants you to say "An enzyme."

How is a catalysts different from a reactant?
a catalyst can affect the rate of a reaction. speeding it up.
What ways can a catalyst affect a chemical reation?
A catalyst affects a reaction by speeding it up. A catalyst, remember, does not participate as a reactant or product in the reaction. It facilitates the reaction by lowering its activation energy, making the reaction easier to happen.
What are the functions of enzymes?
An enzyme is a protein that acts as a catalyst in a living thingEnzymes are proteins which work as a biological catalyst, i.e. increases the rate of the chemical reaction.
The role of catalyst in chemical reaction?
A catalyst speeds up the rate of a chemical reaction.
What are proteins that speed up a chemical reaction in living things?
A catalyst. Definition from Pretence Hall Biology: A catalyst is a protein that speeds up the rate of a chemical reaction.
What protein acts as a catalyst in mediating and speeding a specific chemical reaction?
Enzyme - Logan

What substance increases the rate of a reaction but is not itself changed by the reaction?
It's called a catalyst. A catalyst is present during a chemical reaction but does not participate as a reactant or product. A catalyst lowers the reaction's activation energy, making the reaction easier to happen. In the equation for a chemical reaction, the catalyst's formula appears in small notation above the "yield" arrow (format won't let me show you an example.) An example of a catalyst is potassium iodide (KI) speeding up the decomposition of hydrogen peroxide (H2O2).

How does a catalyst change the rate of a chemical reaction?
Lowers the activation energy of a reaction, therefore speeding the reaction up.Catalysts speed up chemical reactions. They do not change the products or reactants of the reaction, and are not used up or consumed in the reaction. Biological catalysts are called enzymes. Catalysts lower the activation energy (or energy needed to start a reaction), and cause the reaction to occur more quickly.
What do you call a substance speeding up a chemical process?
if at the end of the chemical THAT substance is unchanged .That substance is a catalyst. If it slows donw the reaction, it is called an inhibitor.

What ia a catalyst?
A Catalyst provides an alternate and less complicated pathway or route for reactants to form products in a reaction. An effect of a catalyst is the speeding up or slowing down of the rate of a chemical reaction.It should not be confused with Promoter, which increases the efficiency of a catalyst.
Name two ways to speed up a reaction?
increasing surface area addition of a catalyst
What are catalysts used for?
Catalysts are a complex compound that fastens the rate of reaction when added in a chemical reaction. In a normal chemical reaction, it takes say, 1 hour but while using catalysts, the rate of reaction increases so the resulting time would be less. But making no physical or chemical changes to the reaction. The way a catalyst works is simple. All it does is, absorb the reactant particles onto its surface and absorb their bond energy, making their bonds weaker. In a chemical reaction, Reactant particles need to collide with sufficient kinetic energy to overcome the activation energy for the reaction to proceed. A catalyst lowers the activation energy, so than particles with lower energy can also initiate the reaction.
