Question

Define work, potential energy, kinetic energy

What is the difference between exergonic and endergonic reactions?

What are the 2 laws of thermodynamics? What does entropy mean?

Describe the characteristics of ATP. Include how many phosphates and where the high energy is in the molecule.

What are enzymes?

What are the substrates, the active sites of enzymes?

What is activation energy?

Define denaturation and catalyst

Define catabolism, anabolism

Describe the different inhibitors of enzymes

What does induced fit mean?

1. Work is defined as the vector product of a force and the displacement caused by it in the same direction.

Potential energy is the energy stored in a body by virtue of its position.

Kinetic energy is the energy stored in a body by virtue of its motion.

2. Exergonic reactions liberate energy on occuring while endergonic reactions require or consume energy to occur.

3. The first law, also known as Law of Conservation of Energy, states that energy cannot be created or destroyed in an isolated system.

The second law of thermodynamics states that the entropy of any isolated system always increases.

Entropy- is the degree of randomness of a system, or the amount of energy unavailable to do work.

4. ATP is a nucleotide, which means it is part of the basic structure that makes up DNA and RNA.

One individual unit of ATP is made up of one adenosine molecule with three phosphate connected to it.

ATP is unstable in water, and forms ADP when in water; this formation releases energy and is an additional source of energy in cells

It includes 3 phosphate molecules and these phophate molecules are the source of stored energy since,they are high-energy bonds.

since no question has been specificallly asked, only the first four subparts have been answered.
