Enzymes & Energy

Letter B...

• active site

• enzyme

• substrate

• products

Proteins that play a role in lowering the activation energy necessary for metabolic reactions

• Enzymes

• Hemoglobin

• Reactants

• Substrates

The starting material(s) in a chemical reaction (usually on the left side of a chemical equation)

• Products

• Reactants

What is structure E, F, G?

• Substrate
• Active site
• Enzyme
• Products

Biologists often say that form follows function. That means that the shape of a molecule determines what it does. This similar to using scissors to cut paper, not a spoon, because of the shape of the items. How do we know that the shape of an enzyme determines its function?

• Enzymes are fast.

• Enzymes are specific to their substrate

• Enzymes can be deactivated.

• Enzymes require energy.

In a chemical reaction, ________ are what you have at the end

• Products

• Molecules

• Reactants

• Substances

Which of the possible answers below would not cause the rate of reaction to decrease.

• the enzymes have all denatured

• there is no more substrate in the solution

• more substrate is added to the solution

• inhibitors have bound all of the enzymes

Which of the possible answers below would make the rate of reaction plateau?

• substrate is completely used up

• all enzymes reached saturation

• the enzymes are denaturing

• the enzymes have completely denature

Which answer below displays the characteristics of "activation energy"?

• the energy that is used during a reaction

• the energy needed to start a reaction

• the energy given off from the active site of the enzyme

• only active substrates can supply energy the enzymes need

Since enzymes are proteins, they can lose function and become denatured. What are the two most common ways in which enzymes become denatured?

• Water and Light

• Changes in temperature and pH

• Water and pH

• Light and temperature
