Gluconeaogensis
Glycogenesis
Conversion of pyruvate to acetyl CoA occurs in
Mitochondria
Sucrose is a_______composing of________ and________
Disaccharide; glucose; fructose
During chewing, the enzyme_______ acts on
dietary starch breaking some α1→ 4 bonds
salivary alpha-amylase
The enzyme which breaks glycogen to maltose is
Amylase
The enzyme that breaks maltose to glucose is
Maltase
Glucose and galactose pass through the membrane easily. T/F
False
They need to hitch a ride on a sodium dependent hexose transporter
Fructose hitches a a ride on another hexose transporter and doesn’t require a sodium. T/F
True
Glucose and galactose hitch a ride on the______transporter
SGLT1
Exit from the cell for all sugars is via the
GLUT2
Which family of carriers are used to carry glucose to and from blood
GLUT
GLUT4 is________dependent
Insulin
Insulin stimulates the transport of________into muscle and adipose cells
GLUT4
Glucose is phosphorylated by_______to form glucose 6 phosphate
ATP
Which enzyme catalyze the phosphorylation of glucose to glucose 6-phosphate
Hexokinase
Which enzyme catalyzes the reaction of fructose 6-phosphate to fructose1,6-bisphosphate
Phosphofructokinase 1
The difference between hexokinase and glucokinase is that
Glucokinase mostly acts on the liver and beta cells of the pancreas while hexokinase acts on most other tissues
Inhibitors of phosphofructokinase are
ATP and citrate
