Dropdown

The process of changing a set of chemicals into another set is called a(n)

. The elements or compounds that enter into a chemical reaction is called the

. The elements or compounds produced by a chemical reaction is called the

Dropdown

A substance that speeds up chemical reactions is called a(n)

. A protein in a living organism that acts as a catalyst is called a(n)

. Enzymes work by lowering the amount of energy needed to start a reaction. The energy needed to get a reaction started is called the

Dropdown

Enzymes physically attach to their molecules in order to make chemical reactions work. The elements or compounds that enter an enzyme catalyzed reaction are called

. The area on the enzyme that a substrate binds to is called the

. The physical binding of the enzyme and substrate is called the

Dropdown

The shape of an enzyme is important, because if it changes it can not bind to the substrate anymore. When the shape of a protein, like enzymes, has been changed we say it has been

Multiple Choice

Enzymes are

Proteins

Carbohydrates

Lipids

Nucleic Acids

Multiple Choice

What is the function of an enzyme?

enzymes break themselves into small pieces

enzymes slow down chemical reactions

enzymes speed up chemical reactions

enzymes combine products to form reactants

Multiple Choice

Enzymes work by

Increasing the activation energy

lowering the activation energy

Adding more substrate

By permanently reacting with substrates

Multiple Choice

Which number represents the activation energy?

Multiple Choice

The graph shows how enzymes affect reactions in cells. Which statement best summarizes the information shown in the graph?

Enzymes increase the energy of the reactants.

Enzymes decrease the energy level of the products.

Enzyme decrease the activation energy of the reaction.

Enzymes reverse the direction of the reaction.

Draw

Suppose this is a typical reaction. Draw another path with an enzyme added.

Labelling

Label the parts of the enzyme catalyzed reaction.

Drag labels to their correct position on the image

Products

Enzyme-substrate complex

Substrate

Enzyme

Draw

Circle to active site.

Draw

Draw the substrates for the enzymes.

Multiple Choice

When an enzyme has been denatured it means

The enzyme is more stable and less active.

The enzyme has lost its shape, affecting its activity.

The enzyme can bind more substrates.

The enzyme is now permanently inactive.

Multiple Choice

When an Enzyme has been denatured, it quits working.

True

False

Multiple Select

What factors will denature an enzyme?

Too much substrate

Temperature
