week 5 quiz

fatty acyl coa has to combine with carnitine in order to become fatty acyl carntine but the CoA gets cleaved off in order to attach carnitine

fatty acyl carnitine gets broken down and turned into fatty acyl coA and carnitine carnitine goes back out

1 FDAH
1NADH
Acetyl Coa
Cost
1ATP

the first step of beta oxidation
when you have to add the Coa on the fatty acid

10ATP

4 becuase you get NADH and FADH which goes through the ETC

example if you have a 16 long
then you are going through 7 rounds of beta oxidation and you have 7X4=28
then you are going through 8 acetyl coA so you have 8X 10=80
108 all together and then 107 with the cost

in the inner mito membrane

has 4 complexes
create proton gradient in the intermembrane space

have NADH dump H into it
oxidazes NADH
pump 4 H from matrix to intermembrane space
passes e to CoQ

oxidzes FADH
doesnt add H to the intermembrane space
passes e to CoQ

receives e from the CoQ
becomes charged pump 4 H into intermembrance space
passes e to the cyto C

hydrolyzes oxygen to form H2O (enzyme is Cytochrome oxidase)
pump 4 H into the intermembrane space

forms ATP
energy from proton gradient is used to form ATP

10 H
2.5 ATP

6 H
1.5 ATP

32 if glusoce
33 if glyogen

up tp 20% of CO
during exercise more than 80% of CO to skeletal muscle

vasodilation is to muscle and skin
vasoconstriction is to everything else
heart stays the same

venous blood flow doesnt have the pressure from the pump so uses the muscles to ump blood back up tot he heart
has a valve so that the blood cant rush back down

then bloood will pool and you will pass out becuase of lack of blood to the brain

symtpoms
-muscle cramps
-musle pain muslce damage discolaortion in the urine
-fatigued easily with actitvy
-second wind phenonomon (when aerboic kicks in)
treatment
-no cure
-high fat diet
-timing of digestion
-safe exercise planning
what is it
-bascially you cant break down glyocgen dont have the enzyme for it

load: fixed
muscle ends: fixed
contraclie ends: shortened
elastic elements: stretched

load: fixed
muscle ends: fixed
contractile elements: shortening
elastic elements: stretch

load: moving
musce ends: shortenting so joint angle decreases
contractlie elements: shortening
elastic elements: constant

occurs when the muscle is lengthened
joint angle increases
