The process of building proteins from amino acids is a(n) __________ process.
A:) Anabolic
B:) Catabolic

Answer:
Anabolic.

An anabolic process builds larger molecules from smaller molecules. A catabolic process breaks down larger molecules into smaller molecules.


Which of the following chemical reactions releases energy?
A:) Anabolic Reaction
B:) Endergonic Reaction
C:) Exergonic Reaction

Answer:
Exergonic Reaction.

An exergonic reaction releases energy. An endergonic reaction requires energy. An anabolic process builds larger molecules from smaller molecules. The building process requires an input of energy to form chemical bonds in the new, larger molecule. Energy is released during catabolic reactions as the chemical bonds within molecules break apart.


Which molecule allows the transfer of energy from exergonic reactions to endergonic reactions.
A:) ATP
B:) DNA
C:) Glucose
D:) HMB

Answer:
ATP.

ATP is an intermediary molecule that allows energy to be transferred in the body. Energy is obtained from exergonic reactions and used in endergonic reactions. DNA is genetic information contained in the nucleus of cells. Glucose is a monosaccharide. HMB is a dietary supplement.


Which of the following is not a component of ATP?
A:) Adenine
B:) Glucose
C:) Phosphate
D:) Ribose

Answer:
False.

Glucose. Adenosine triphosphate (ATP) is composed of three main components: Adenine – a nitrogen-containing organic base, which is also one of the four bases found in DNA and RNA. Ribose – a five-carbon sugar molecule that is a component of RNA. Three phosphate groups – which are composed of one phosphorus atom and four oxygen atoms each.

The three phosphate groups are bonded to the ribose sugar molecule, with the adenine base attached to the ribose sugar. This structure of ATP is important because the high-energy bonds between the phosphate groups can be broken to release energy that can be used by cells for various processes.


How many molecules of water are required to break down one molecule of ATP?
A:) 1
B:) 2
C:) 3
D:) 4

Answer:
1.

ATP hydrolysis refers to the chemical process by which ATP (adenosine triphosphate) is broken down into ADP (adenosine diphosphate) and inorganic phosphate (Pi). This reaction releases energy that can be used for various cellular processes, such as muscle contraction, active transport of molecules across cell membranes, and the synthesis of molecules like proteins and nucleic acids.

The reaction for ATP hydrolysis can be represented as follows:

ATP + H2O → ADP + Pi + energy

In this reaction, a water molecule is used to break the bond between the second and third phosphate groups of ATP, resulting in the release of energy and the formation of ADP and Pi. The energy released during this process can be harnessed by the cell to drive various biochemical reactions that require energy.


Which of the following is not one of the three basic energy systems to replenish ATP in muscle cells?
A:) Glycolysis
B:) Hydrolysis
C:) Oxidative
D:) Phosphagen

Answer:
Hydrolysis.

The three basic energy systems that replenish ATP in human muscle cells are the Phosphagen System, Glycolysis, and the Oxidative System. Hydrolysis is the process that removes a terminal phosphate group from ATP to release energy.


Which of these main macronutrients can be metabolized for energy without the direct involvement of oxygen?
A:) Carbohydrates
B:) Fats
C:) Protein

Answer:
Carbohydrates.

Carbohydrates are the macronutrient that can be metabolized for energy without the direct involvement of oxygen. This process is known as anaerobic glycolysis. During anaerobic glycolysis, glucose is broken down into pyruvate, which is then converted into lactate or lactic acid, without the use of oxygen. This process occurs in the cytoplasm of cells and produces a small amount of ATP, which is the main source of energy for cells. However, anaerobic glycolysis is not as efficient as aerobic respiration, which requires oxygen and produces much more ATP.


Skeletal muscle concentrations of creatine phosphate are approximately four to six times __________ than ATP concentrations.
A:) Higher
B:) Lower

Answer:
Higher.

There is more creatine phosphate than ATP in skeletal muscle because the phosphagen system uses creatine phosphate to rapidly replenish ATP stores to maintain energy levels.


Which type of carbohydrate is pulled from the blood to be used by glycolysis in muscle cells?
A:) Galactose
B:) Fructose
C:) Glucose
D:) Sucrose

Answer:
Glucose.

The carbohydrate that is pulled from the blood to be used by glycolysis in muscle cells is glucose. Glucose is a monosaccharide and a simple sugar that is easily transported through the bloodstream and taken up by muscle cells for energy production. Once inside the muscle cell, glucose undergoes a series of reactions through the process of glycolysis to produce ATP, the primary source of energy for muscle contractions.


 

 

CSCS Questions: Chapter 3: Bioenergetics of Exercise & Training

Chapter 3 of the Essentials of Strength Training & Conditioning (4th edition) textbook was written by Trent J. Herda, Ph.D. and Joel T. Cramer, Ph.D. This chapter contains a general overview of bioenergetics that will be relevant for taking the Certified Strength and Conditioning Specialist (CSCS) exam. This chapter covers ATP, basic energy systems of the body, lactate accumulation, metabolic acidosis, fatigue, substrate depletion and repletion, bioenergetic limitations, training for metabolic specificity, metabolic demands and recovery, and optimization of work-to-rest ratios.

This page contains Certified Strength Conditioning Specialist questions  to prepare for the National Strength and Conditioning Association (NSCA) Certified Strength and Conditioning Specialist (CSCS) exam. Certified strength and conditioning specialists are fitness professionals. They are specially trained and experienced in using the application of scientific principles to improve athletic performance. Certified strength and conditioning specialists assist athletes by designing and implementing strength and conditioning programs. Certified strength and conditioning specialists (CSCS) conducting sport-specific performance testing, provide guidance with nutrition, and assist with injury prevention strategies (NSCA, 2015).

Certified Strength and Conditioning Specialist Exam

The Certified Strength and Conditioning Specialist (CSCS) exam by the National Strength and Conditioning Association (NSCA) is a four-hour-long, pencil and paper or computer-based examination. The Certified Strength and Conditioning Specialist exam has two sections: “Scientific Foundations” and “Practical / Applied.” Each of these sections consist of questions that the National Strength and Conditioning Association (NSCA) feels are relevant to test the knowledge and experience of a candidate for the Certified Strength and Conditioning Specialist (CSCS) professional credential. Certified strength conditioning specialist questions in the Scientific Foundations section include anatomy, exercise physiology, biomechanics, and nutrition. Certified strength conditioning specialist questions in the Practical / Applied section include program design, exercise techniques, testing and evaluation, and organization / administration (NSCA, 2015).

Certified Strength Conditioning Specialist Questions

This quiz features Certified Strength and Conditioning Specialist Exam Questions: Chapter 2 material: Bioenergetics of Exercise and Training from Essentials of Strength Training & Conditioning (3rd edition) textbook by Thomas R. Baechle and Roger W. Earle. This is the National Strength and Conditioning Association (NSCA) recommended textbook to prepare for the Certified Strength and Conditioning Specialist (CSCS) exam (NSCA, 2015)
