What role do enzymes play in metabolic pathways?

• They inhibit chemical reactions

• They catalyze specific chemical reactions

• They destroy molecules

• They act as products

What is potential energy?

• Energy of motion

• Energy due to location or structure

• Energy released in a chemical reaction

• Energy from the sun

What is chemical energy?

• Kinetic energy due to random movement of atoms

• Potential energy available for release in a chemical reaction

• Energy stored in the nucleus of an atom

• Energy from electromagnetic waves

What does the First Law of Thermodynamics state?

• Energy can be transferred and transformed, but it cannot be created or destroyed.

• Energy can be created and destroyed.

• Energy is always increasing in the universe.

• Energy cannot be transferred or transformed.

What is the principle of conservation of energy?

• Energy in the universe is constant.

• Energy can be created from nothing.

• Energy is always increasing.

• Energy can be destroyed.

What does the Second Law of Thermodynamics state about energy transfer?

• It decreases the entropy of the universe.

• It increases the entropy of the universe.

• It has no effect on the entropy of the universe.

• It makes the universe more ordered.
