ENERGY PRODUCTION FOR CONTRACTION (will be a matching section)

Question 1

What are the 3 types of ENERGY PRODUCTION FOR CONTRACTION

Answer 1

1. Phosphagen System 2. Anaerobic Metabolism 3. Aerobic Metabolism

Question 2

Muscle stores a substance know as creatine phosphate (CP) that is used to create ATP (energy) when ATP is running low.

Answer 2

Phosphagen System

Question 3

. It is an anaerobic process because it doesn’t use oxygen

Answer 3

Anaerobic Metabolism

Question 4

At rest a muscle contains six times more CP as it does ATP. Without CP, muscle only contains enough ATP for about 5 seconds of contractions because it’s used up as quickly as it is made.

Answer 4

Phosphagen System

Question 5

This process uses sugars, proteins, and fats to produce ATP.

Answer 5

Aerobic Metabolism

Question 6

This process only uses sugars to produce ATP.

Answer 6

Anaerobic Metabolism

Question 7

CP is especially important during periods of intense exercise when the ATP supply is limited. As a result, the phosphagen system is the first method used to produce energy during exercise once ATP has been used up.

Answer 7

Phosphagen System

Question 8

It is an aerobic process because it requires oxygen.

Answer 8

Aerobic Metabolism

Question 9

Without oxygen, only a small amount of ATP can be produced:

Answer 9

Anaerobic Metabolism

Question 10

With oxygen, a large amount of ATP can be produced:

Answer 10

Aerobic Metabolism

Question 11

This method is often used during activities that have on & off bursts of muscle contraction, as in tennis, soccer.

Answer 11

Anaerobic Metabolism

Question 12

*It occurs in special cell compartments that store oxygen called mitochondria.

Answer 12

Aerobic Metabolism

Question 13

It is used first to produce more energy b/c it is much faster than the other 2 methods.

Answer 13

Phosphagen System

Question 14

An advantage to this method is that it produces energy quickly. Because of this, it is the second method used to produce ATP during exercise.

Answer 14

Anaerobic Metabolism

Question 15

Its only disadvantage is that it is a rather slow process. Because of this, it is the last method used to produce ATP during exercise. However, it is the most important method because it produces the bulk of the ATP needed for muscle contraction.

Answer 15

Aerobic Metabolism

Question 16

Another disadvantage to this method is that a waste product _________________ is made, causing burning and pain in muscle. Also what energy production is it?

Answer 16

Lactic Acid Anaerobic Metabolism

Question 17

1CP → 1ATP

Answer 17

Phosphagen System

Question 18

1 Glucose → 2 ATP

Answer 18

Anaerobic Metabolism

Question 19

1 Glucose → 36 ATP

Answer 19

Aerobic Metabolism

Question 20

provides energy for the
first 15 seconds of
muscle contraction.

Answer 20

Phosphagen System

Question 21

provides energy for hours
of muscle contraction.

Answer 21

Aerobic Metabolism

Question 22

provides energy for
about a minute of muscle
contraction (together
with CP and stored ATP).

Answer 22

Anaerobic Metabolism

Question 23

ATP can’t be stored in muscle. But _____ Can be stored.

Answer 23

Creatine Phosphate (CP)

Question 24

What is the best way of energy production? What is the draw back?

Answer 24

Aerobic Metabolism

The drawback is this is the slowest way.
