31Muscle glycogen gives [blank_start]immediate[blank_end] energy, metabolism is done directly by [blank_start]cell[blank_end], its the [blank_start]primary energy[blank_end] for an athlete. Liver glycogen gives [blank_start]short term [blank_end]energy storage for [blank_start]muscle and brain[blank_end], metabolism is done by [blank_start]glucose phosphatase[blank_end] and stores are [blank_start]half used[blank_end] after 1 hour of intense exercise.
- Aimmediate
- Bcell
- Cprimary energy
- Dshort term
- Emuscle and brain
- Fglucose phosphatase
- Ghalf used
32Simple carbs have [blank_start]rapid[blank_end] absorption, rapid [blank_start]increase[blank_end] in blood glucose, [blank_start]strong[blank_end] increase in insulin and glucose is stored as glycogen and [blank_start]fat[blank_end] because [blank_start]TCA cycle[blank_end] is saturated with [blank_start]acetyl Co A[blank_end]. Complex carbs have a [blank_start]slow[blank_end] absorption and slow increase in blood glucose, they have a [blank_start]lesser[blank_end] insulin response and maximize [blank_start]glucose[blank_end] stored as [blank_start]glycogen[blank_end]. [blank_start]Complex carbs[blank_end] are preferred for athletes.
- AComplex carbs
- Bsimple carbs
- Crapid
- Dslow
- Estrong
- Flesser
- Gglucose
- Hglycogen
- Ifat
- JTCA cycle
- Kacetyl Co A
- Lincrease
