Chapter 8 - Exercise Metabolism and Bioenergetics

Question 1

What is ATP?

Answer 1

Adenonsine Triphosphate - the main form of energy in the human body

Question 2

What is the first law of thermodynamics?

Answer 2

Energy can either be treated nor destroy, only recycled or converted from one form into another

Question 3

what are macronutrients?

Answer 3

Food substances required in large amounts to supply energy, i.e. protein, carbohydrates, and fats

Question 4

glucose

Answer 4

A main source of energy, particularly for brain function and higher intensity activity. It can be made in the body from other substrates (fats and amino acids), but a large majority of our daily needs comes from carbs which are broken down and into glucose to digesting.

Question 5

glycogen

Answer 5

Restored and deliver and muscle Sales and Kim broken down rapidly to provide energy when there is not enough pre-glucose in the blood

Question 6

the point of which the body uses an equal mix of carbs and fat as fuel sources

Answer 6

VT1

Question 7

the point where glucose provides nearly all the energy for the activity

Answer 7

VT2

Question 8

triglycerides

Answer 8

Derive directly from fats containing foods or made by the body to store excess energy when more food is consumed that is needed to support activity

Before can be consumed or stored as fuel and must be broken down into free fatty acids. They are use exclusively and the aerobic metabolic pathway to produce ATP

Question 9

How many total amino acids?

Answer 9

20

Question 10

What are essential amino acids?

Answer 10

The body cannot synthesize them on his own and must be consumed in a diet

Question 11

How many essential amino acids?

Answer 11

9

Question 12

ATP-PC System

Answer 12

an energy system that provides energy very rapidly for approximately 10-15 seconds via anaerobic metabolism
