Carbohydrates: An organic compound that is the primary supporting tissue for plants.
Glucose: This is a sugar that can come in many different forms. It occurs primarily in tissues, fluids, and fruits. The primary end product is after the digestion of carbohydrates.
Glycogen: This is a polysaccharide that is tasteless and white and is the primary carbohydrate storage in mammals. It occurs primarily in the muscles as well as in the liver.
Fat: This type of organic compound is insoluble in water but soluble in alcohol and ether. Fats are comprised of lipids and our greasy to the human touch.
Triglycerides: These are three fatty acids that connect to glycerol. This makes up most of the fat storage in the human body.
Protein: Multiple linked amino acids (20+) in a linear sequence that form one or more polypeptide chains.
Gluconeogenesis: When glucose is formed from a non-carbohydrate such as fats or protein.
Energy for work
Adenosine triphosphate: The transfer and energy storage unit inside the body’s cells. When the chemical bonds that hold together ATP break, energy is released for work such as muscle contraction. When this bond breaks, it leaves behind ADP (Adenosine diphosphate).
Adenosine diphosphate: This is a high energy compound from which ATP is formed.
Beta (B)-oxidation: This is the first process that breaks down fatty acids. It includes the oxidation of beta carbons and removing carbon fragments from the fatty acid.
EPOC (Excess Post-exercise oxygen consumption): Metabolism will elevate after higher intensity exercises. The reason that you see high-intensity interval training as a successful method for shedding fat. High-intensity work will increase EPOC.

How important is it to know overactive and underactive muscles?
Hey Nakia,
The overactive and underactive muscles are extremely important for the NASM exam. You will see approximately 10 questions just on the overhead squat assessment alone so pay close attention to these.
Thank you for your free NASM study guide. Question, by focusing on chapters4,5,and 10, how many test questions can I answer? What other chapters are most important. Thank you in advance for your generous help?
That will definitely cover a decent amount, but you won’t be able to pass the test just by knowing those chapters. I would say the most important chapter is chapter 6 out of all of them. Also there are a good amount of questions on nutrition as well. Good luck!
