Chapter 4 and 5

Question 1

Substrates

Answer 1

The material or substance on which an enzyme acts.

Question 2

ATP-PC/Phosphagen system

Answer 2

Simple, fast.
Crates ATP from a phosphocreatine molecule
Lasts 10 to 15 seconds

Question 3

Glycolysis

Answer 3

ATP produced braking down glucose.
Glucose/Glycogen is broken down into glucose-6-phosphate.
It takes 1 ATP to convert glucose into glucose-6-phosphate Glycogen it does not.
Produces more energy overall than Phosphagen system. Lasts 30-50 seconds.

Question 4

Oxidative pathway

Answer 4

Glycolosis
Glucose–>Pyruvic acid–>Krebs Cycle–>Electron transport chain. Each step produces ATP
Complete metabolism of one glucose molecule produces 35 to 40 ATP

Question 5

Frontal Plane

Answer 5

Side to side movements

Question 6

Sagittal Plane

Answer 6

Forward and backward movements, pushing pulling

Question 7

Transverse Plane

Answer 7

Rotational, and diagonal movements.

Question 8

Eccentric muscle action

Answer 8

an eccentric muscle action occurs when a muscle develops tension while lengthening.

Question 9

Concentric muscle action

Answer 9

when a muscle is exerting force greater than the resistive force, resulting in shortening of the muscle

Question 10

Isometric muscle action

Answer 10

When a muscle is exerting force equal to the force being placed on it leading to no visible change in the muscle length.

Question 11

Isokinetic muscle action

Answer 11

when a muscle shortens at a constant speed over the full range of motion. Usually involving a very expensive piece of equipment.
