Question 13

What are three characteristics of triglycerides?

Answer 13

• Reduced (lots of electrons)
• Anhydrous (no water)
• 9kcal/gram

Question 14

Where are the vast majority of triglycerides stored?

Answer 14

Subcutaneous and visceral adipose tissue

Question 15

Which muscle fibers store 2-3 times more fat than the other? Type I or type II?

Answer 15

Type I (aerobic) store more than type II

Question 16

These are a fat-storage depot if there are a lot of lipid’s available and can be used as a source of fatty acids during exercise.

Answer 16

Intramuscular triglycerides (IMTG)

Question 17

Replenishment of intramuscular triglycerides can be impaired and remain below pre-exercise levels until 72 hours after this type of exercise.

Answer 17

Aerobic exercise

Question 18

Replenishment of intramuscular triglycerides following this type of exercise appears to be rapid and occurs within a few hours.

Answer 18

Resistance exercise

Question 19

Increased content of triglyceride synthesizing enzymes after a single bout of aerobic exercise explains ____ of intramuscular triglycerides concentration that occurs following intramuscular triglyceride depletion during exercise.

Answer 19

Supercompensation

Question 20

Which group has lower intramuscular triglyceride concentrations and moderate insulin insensitivity? Normal people, athletes, obese people?

Answer 20

Normal people

Question 21

Which group has elevated oxidative capacity, higher concentrations of intramuscular triglyceride, and greater insulin insensitivity? Normal people, athletes, obese people?

Answer 21

Athletes

Question 22

Which group has higher intramuscular triglyceride concentrations and low insulin insensitivity? Normal people, athletes, obese people?

Answer 22

Obese people

Question 23

What is the first step of converting triacylglycerol into free fatty acid?

Answer 23

Triacylglycerol (TAG) is converted into diacylglycerol (DAG) by aidpose triglyceride lipase (ATGL)

Question 24

After triacylglycerol is converted into diacylglycerol, what is the next step in creating free fatty acid?

Answer 24

Diacylglycerol (DAG) is converted into monoacylglycerol (MAG) by hormone sensitive lipase (HSL)

Question 25

After diacylglycerol is converted into monoacylglycerol, what is the next step in creating free fatty acid?

Answer 25

Monoacylglycerol (MAG) is converted into free fatty acid (FFA) by monoacylglycerol lipase (MGL)

Question 26

What is the first step of converting free fatty acid into triacyl glycerol?

Answer 26

Free fatty acid (FFA) and glycerol is converted into monoacylglycerol (MAG) by glycerol-3-phosphate acyltransferase (GPAT)

Question 27

After free fatty acid is converted into monoacylglycerol, what is the next step in creating triacylglycerol?

Answer 27

Monoacylglycerol (MAG) is converted into diacylglycerol (DAG) by acylglycerol-3-phosphate acyltransferase (AGPAT)

Question 28

After monoacylglycerol is converted into diacylglycerol, what is the next step in creating triacylglycerol?

Answer 28

Diacylglycerol (DAG) is converted into triacylglycerol (TAG) by diacylglycerol acyltransferase (DGAT)

Question 29

These are proteins that break down lipoproteins at the surface of capillaries. They are produced by muscle and fat cells and release fatty acids into tissues.

Answer 29

Lipoprotein lipases

Question 30

Does exercise increase of decrease skeletal muscle LPL?

Answer 30

Increases it, while reduced activity causes up to a 10 to 20-fold decrease in LPL activity.
