8. Anaerobic means ________.

9. When a person performing intense physical exercise begins to feel fatigue and a burning pain in the muscles, the muscles respond by synthesizing more of what substance? (Lactate vs. glucose vs. fatty acids?)

10. True or False: Low carbohydrate diets induce ketosis

11. An individual is described as ________ when they have the endurance to engage in daily activities, as well enough reserve energy to handle added challenges.

12. A minimum of ______ minutes at a time of aerobic physical activity is recommended per activity session.

13. ________ refers to an increase to the size and strength of muscles in response to use.

14. True or False: Putting a demand on muscles repeatedly by making them work harder is the most effective, safe way for athletes to add muscle tissue.

15. According to ACSM guidelines, resistance or strength exercise should be incorporated on ________ per week.

16. An athlete getting ready to compete in the 100-meter dash will rely primarily on what substance for quick energy in this event? (Fats vs. lactate vs. creatine phosphate?)

17. The body’s primary source of glucose during physical activity is ________.

18. True or False: With regards to the energy systems and fuels used by the body, all energy systems are used at all times, but one system which dominates depending on intensity and conditioning of athlete.

19. What type of diet does research suggest can provide endurance athletes with ability to go longer without fatigue?

20. ________ are the dietary nutrients most effective at raising muscle glycogen concentrations.

21. Activities lasting longer than 20 minutes will gradually start using more ________ for fuel and less ________.

22. True or False: Consuming a sports beverage to obtain carbohydrates is recommended during exhausting endurance activities lasting more than 1 hour.

It’s recommended that an athlete

Answer 1

* Metabolism is a term that is used to describe the bio-chemical reactions that take place in living cells and are essential for the survival of living organisms.

* Catabolism. It is the category of metabolism in which larger molecules are broken down into smaller ones.

* Yes. Anabolic reactions are the other category of metabolism, in which smaller molecules join to form larger, complex molecules. Amino acids are the building blocks of proteins.

* Glucose. It is the simplest sugar and living cells can use it to produce energy in the form of ATP.

* CoA is synthesized from Vit B₅, called pantothenate. Foods such as meat, cereals, legumes, milk, and eggs are rich in vit B₅

* Aerobic metabolism takes place in the mitochondria of the cells in the presence of oxygen. The reaction ends with the net production of H2O, CO2 and an ample amount of ATP, depending on the substrate which has been oxidized [ sugar, fats or proteins].

* Anaerobic pathway is the main energy provider during short, intense exercises.

* Anaerobic means without air or without oxygen. It is a respiration pathway by which sugar is broken down in the cytoplasm in the absence or presence of very little oxygen.

* Lactate

* True. Due to low carbohydrate diet for a long time, the body's glycogen store becomes depleted and the body starts using fats as fuel to produce energy.
