Biology 101 Exam 2 questions with
correct answers 2026
All of an organisms' chemical reactions - CORRECT ANSWERS -Metabolism
A____ _____begins with a specific molecule & ends with a product. - CORRECT ANSWERS -
Metabolic Pathway
The study of energy transformations - CORRECT ANSWERS -Thermodynamics
First law of thermodynamics - CORRECT ANSWERS -Energy can be transferred & transformed,
but it cannot be created or destroyed.
Second law of thermodynamics - CORRECT ANSWERS -Every energy transfer or transformation
increases the entropy(disorder) of the universe.
A living cell's____ ____is energy that can do work. - CORRECT ANSWERS -Free Energy
Exergonic Reaction - CORRECT ANSWERS --Spontaneous
- results Ina net release of free energy
Endergonic Reaction - CORRECT ANSWERS -- non-spontaneous
- absorbs free energy from its surroundings.
The use of an exergonic process to drive an endergonic one. - CORRECT ANSWERS -Energy
Coupling
, ATP is composed of? - CORRECT ANSWERS -- Ribose (a sugar)
- Adenine ( a nitrogenous base)
- 3 P groups
The initial energy needed to start a chemical reaction - CORRECT ANSWERS -Activation Energy
The reactant that an enzyme acts on? - CORRECT ANSWERS -Substrate
The region on the enzyme where the substrate bonds? - CORRECT ANSWERS -Active Site
A substrate brings chemical groups of the active site into positions that enhance their ability
to catalyze the reaction. - CORRECT ANSWERS -Induced Fit
Cofactors - CORRECT ANSWERS -- non-protein enzyme helpers
- may be inorganic or organic
Coenzyme - CORRECT ANSWERS -- organic cofactors
i.e. Vitamins
Substances that block an enzyme's active site - CORRECT ANSWERS -Inhibitors
3 types of inhibitors - CORRECT ANSWERS -1. Competitive Inhibition
2. Allosteric Inhibition (non-competitive)
3. Feedback Inhibition
