2nd storage of energy + generation of ATP in Skeletal Muscle tissue for MUSCLE CONTRACTIONS

2ND method of GENERATING Atp for MUSCLE CONTRACTION

[ glycolysis / anaerobic process ]

[ GLYCOLYSIS ]

ANAEROBIC Process

[ oxidative phosphorylation ]

(*remember the ELECTRON TRANSPORT TRAIN etc is where we MAKE THE MOST ATP ) generating Electron carriers NADH and FADH

GLYCOLYSIS (is an ANAEROBIC process) so NO oxygen O2 needed

whole process because NOT MUCH ATP can LAST between 45 -50 SECONDS

GLYCOLYSIS IS

process of breaking Glucose down

• we took GLUCOSE and BROKE IT DOWN

• producing two Pyruvates and ALSO releases ATP

• and generated some NADH

glucose comes from bloodstream, INSULIN, and what we eat

; MUSCLES STORES GLUCOSE

in the form OF GLYCOGEN - a carbohydrate storage

sprint then jog sprint then job - process of glycosys similar in pause

sometimes our body will take PYRUVATE and

CONVERT INTO LACTIC ACID BUILDUP

gives burning sensation and CAUSES BREATHING HARD

BREATHING HARD because body is trying to get CARBON D IN BLOOD

Kidneys will also try to get rid of buildup of lactic acid

GLYCOLYSIS IS GENERATING ATP

doesn’t need oxygen

can break down glucose from bloodstream or what we eat

into PYRUVATE when pyruvate breaking releasing atp energy

[ OXIDATIVE PHOSPHORYLATION ]

happens through ELECTRON TRANSPORT TRAIN
ETC

OXIDATIVE PHOSPHORYLATION - makes most atp think of other 2 as back ups in ox 2 is running low

etc is where we make the MOST ATP

this DOES REQUIRE OXYGEN

use things like fatty acid , pyruvate that we’ve made and amino acid

CAN be USED

by getting the ELECTRONS GENERATING ELECTRON CARRIERS

all those migrated in Electron Transport Chain ETC

collect electrons using ELECTRON CARRIERS

electron carriers (FAHD and NAHD) are going to carry electrons and build up of energy to the etc where you will generate the MOST ATP
