|
what are the 3 monosaccharides
|
1) glucose
2) fructose 3) galactose |
|
|
what are the 3 dissacharides
|
1) sucrose
2) maltose 3) lactose |
|
|
what are the 3 polysacharides
|
1) starch
2) cellulose 3) glycogen |
|
|
what form do we store CHO as
|
glycogen
|
|
|
what form do we usually consume CHO as
|
starch
|
|
|
what is our primary fuel source
|
CHO (but we consume mostly complex carbs, that we cant use --> they have to be broken down into simple sugars
|
|
|
how does our body store glucose, and why can't it be stored simply as glucose
|
glucose itself is toxic to the cells, so we convetert it to glycogen to be stored
|
|
|
if a cell is not currently "working" what is happening to glucose
|
the cell is anabolically transfering glucose to glycogen
|
|
|
if a cell is currently "working" what is happening to glucose
|
the cell is catabolically converting it to energy
|
|
|
where are the stores of CHO, and how much / store
|
1) most is stored in the muscle 200-300 g of glycogen
2) liver 80-100 g 3) blood 10 g |
|
|
each gram of carbs = how much kcal
|
1 g carb = 4 kcal energy
|
|
|
what receptor does glucose act on to enter the cell
|
Glut4 (skeletal muscle)
|
|
|
what effects does exercise have on the Glut 4
|
exercise is synergistic to insulin.... so when we exercise we stimulate the Glut4 to bring glucose into the cell
|
|
|
During glycolysis, G6P is produced from what 2 sources
|
1) blood glucose
2) muscle glycogen |
|
|
what is the end phate of G6P
|
metabolized to pyruvate
|
|
|
1 glucose = ___ pyruvate
|
1 glucose = 2 pyruvate
|
|
|
what two systems do NOT require oxygen
|
phosphagen and glycolsis
|
|
|
what system is fermenatation
|
glycolysis
|
|
|
what is the net result of ATP for glycolysis
|
2 ATP
|
|
|
what are the end products of glycolysis
|
pyruvate or lactate
|
|
|
what activities use glycolysis
|
high intensity, low duration
|
|
|
what activates glycolysis
|
1) hormones
2) SNS 3) intracellular metabolic waste produces |
|
|
glycolysis is a _______ process, meaning
|
cystolic process- meaning that it occurs WITHIN the cell's cytoplasm
|
|
|
what stimulates glycolysis
|
ADP, Pi, AMP
|
