EEP Exam 1 (material start: 9/12/23) Flashcards
Currency of energy
ATP
must fuel muscle beyond:
homeostasis/resting
dietary high energy phosphate sources:
CHO, Fat, Protein, creatine phosphate (CP), glycogen
aerobic metabolism is ______ than anaerobic metabolism. why?
Slower. it involves the cytosol and mitochondria and is used for a longer amount of time, but with a less strenuous workout.
examples of aerobic exercise:
walking, swimming laps, slow jogging
oxygen is needed for phosphorylation. Which one?
oxidative phosphorylation
cells do not need to produce ATP as quickly during:
aerobic metabolism
the more fit you are____:
the longer you are able to stay in aerobic
anaerobic metabolism is _____ than aerobic metabolism. why?
faster; because there is a higher decree of exercise
examples of anaerobic exercise
sprinting, HIIT, weightlifting
anaerobic metabolism has a ______ glycolysis. Resulting in:
fast; more overall lactic acid
what are the types of skeletal muscle?
Type 1, Type 2, Type 2a, and type 2b
is type 1 skeletal muscle more aerobic or anaerobic?
aerobic
is type 2 skeletal muscle more aerobic or anaerobic?
anaerobic
list at least 3 factors that contribute to a substrate choice
intensity of exercise, duration of exercise, fitness of individual, and nutritional status
what is the preferred energy source?
fat
what does it mean when someone says “aerobic exercise?” what happens to the fat in the body? glycolysis?
lower levels of exercise where training increases fat utilization and muscle glycogen is primary.
as blood glucose increases during exercise….
the more the body will rely on fat
blood glucose will circulate from liver unless
postprandial
what does it mean when someone says “aerobic exercise?” what happens to the fat in the body? glycolysis?
a higher intensity workout, where glycogen is used to replace blood glucose and blood glucose is used first.
what is the only substrate choice for anaerobic exercise?
CHO
what happens during anaerobic exercise when the only substrate is CHO?
glycogen will replace the blood glucose and blood glucose will be used first
what happens during anaerobic exercise when creatine phosphate is present?
a quick phosphorylation of ADP. this is the first and fastest way
