ch 10 pt 6 anatomy

Question 1

What is myokinase?

Answer 1

Phosphate transferred from one ADP to another to make ATP

Question 2

3 ways to generate additional ATP in skeletal muscle fiber?

Answer 2

Creatine phosphate, glycolysis, aerobic cellular respiration

Question 3

What is myoglobin?

Answer 3

A protein found in skeletal muscle that helps store and transport oxygen

Question 4

What is creatine phosphate?

Answer 4

Immediate energy source, phosphate can transfer to ADP to form ATP

Question 5

What is glycolysis?

Answer 5

Short-term energy source, no oxygen needed, glucose is converted to two pyruvate molecules, occurs in cytosol

Question 6

What is aerobic cellular respiration?

Answer 6

Requires oxygen, long-term energy source in the mitochondria - myoglobin,

Question 7

What is lactate dehydrogenase?

Answer 7

Pyruvate converted to lactate

Question 8

Lactic acid cycle

Answer 8

Cycling of lactate to liver where it converts to glucose and transports back to muscle

Question 9

What is oxygen debt?

Answer 9

Amount of additional oxygen needed after exercise

Question 10

Skeletal muscle fibers classified based on

Answer 10

Type of contraction generated and means for supplying ATP

Question 11

What is type of contraction generated?

Answer 11

Differences in power, speed, and duration

Question 12

What is fast-twitch fibers?

Answer 12

Powerful, quick, brief contraction

Question 13

What is slow-twitch fibers?

Answer 13

Not as powerful, slow, longer contraction

Question 14

Primary means for supplying ATP

Answer 14

Oxidative versus glycolytic fibers

Question 15

What are oxidative fibers?

Answer 15

Cellular respiration, red fibers, lots of blood vessels

Question 16

What are glycolytic fibers?

Answer 16

Glycolysis, white fibers, fatigable
