A 16-year-old adolescent boy on the track team asks
his pediatrician if he can take creatine on a regular
basis in order to increase his muscle strength prior
to a track meet. Which of the following most likely
explains why he wants to take creatine?
A. Creatine delays the metabolism of fatty acids.
B. Creatine increases muscle glycogen concentration.
C. Creatine increases plasma glucose concentration.
D. Creatine is converted to phosphorylcreatine.
E. Creatine prevents dehydration by increasing
creatinine formation.
mellitus presents for his annual checkup. Serum
lipoprotein analysis done after a 12-hour fast shows
elevated lowdensity lipoprotein (LDL) and very lowdensity
lipoproteins (VLDL), elevated triglycerides,
and decreased high-density lipo-protein cholesterol.
What contributes to the lipid abnormalities in type 2
diabetes mellitus?
A. Hyperglycemia increases triglyceride uptake into
adipose tissue.
B. Insulin resistance increases triglyceride uptake
into adipose tissue.
C. Insulin resistance and hyperglycemia decrease
fatty acid flux to the liver and lipolysis.
D. Insufficient insulin action in adipose tissue
decreases lipoprotein lipase activity.
E. Insufficient insulin action increases LDL receptor
activity.
