|| || || || || || || || || || || || ||
carbohydrate intake is consumed for 6 days before an athletic event while
|| || || || || || || || || || || ||
tapering exercise duration in an attempt to increase muscle glycogen stores.
|| || || || || || || || || ||

✔During the week prior to the event, the athlete gradually reduces the intensity
|| || || || || || || || || || || ||
and duration of workout ("tapering") while simultaneously increasing the
|| || || || || || || || || ||

|| || || || || || || || || || || ||
glycogen stores (increases stores by 50% to 85% over typical conditions)

|| || || || || || || || || || || || || ||
a day while athletic folk need even more fluids
|| || || || || || || ||

, 2

What happens during anaerobic glucose metabolism? - Correct answer
|| || || || || || || || ||
✔glucose is broken down into a three-carbon compound called pyruvic acid
|| || || || || || || || || || ||
which is accumlated and then converted to lactic acid
|| || || || || || || ||
What happens during aerobic glucose metabolism? - Correct answer ✔the
|| || || || || || || || || ||
pyruvic acid is shuttled to the mitochondria of the cell where it is fully
|| || || || || || || || || || || || || ||
metabolized into carbon dioxide and water || || || || ||
When do you use anaerobic glucose metabolism? - Correct answer ✔events that
|| || || || || || || || || || ||
require a quick burst of energy, ranging from about 30 seconds to 2 minutes
|| || || || || || || || || || || || || || ||
(limited oxygen available to muscles) || || || ||
When do you use aerobic glucose metabolism? - Correct answer ✔Activities
|| || || || || || || || || || ||
that last anywhere from 2 minutes to 3 hours or more (plenty of oxygen
|| || || || || || || || || || || || || ||
