What is the storage form of carbohydrate?
Which is bigger, proglycogen or macroglycogen?
Which form of glycogen is more sensitive to dietary carbohydrate?
Which form of glycogen is synthesized more rapidly following post exercise glycogen depletion?
When does post exercise synthesis of proglycogen reach a plateau?
after 24 hours
Which form of glycogen is synthesized slowly and constantly?
When does synthesis of macroglycogen occur?
for at least 48 hours post exercise
Which form of glycogen is responsible for carb loading?
What is the storage form of glucose in animals?
What bonds are most frequent in glycogen?
What type of bonds are a1-4 and a1-6 bonds?
What bond forms the branches of glycogen?
How many bonds in glycogen are a1-6?
1 out of about 10
What is the purpose of branching in glycogen?
increases solubility and gives it more accessible surface area to "eat"
What is the first carbon in D-Glucose?
the one double bonded to O and single bonded to one H
What is the first carbon in a-D-Glucopyranose?
to the right and down to the O
Where does an a1-4 bond take place?
between the 1 carbon of a glucose and the 4 carbon of another
What are the two types of starch?
amylose and amylopectin
Is amylose branched or unbranched?
What bond takes place in amylose?
Is amylopectin branched or unbranched?
What bonds take place in amylopectin?
a1-4 and a1-6
How often do we see an a1-6 bond in amylopectin?
every 30 a1-4 bonds
How much glycogen is stored in skeletal muscle?
How much glycogen is stored in the liver?
How much glycogen is stored in other cells?
Where is glycogen stored in the cell?
Why is glucose trapped in muscle?
it lacks the enzyme needed to release glucose
How much glucose is not fully accessible during exercise?
about 1600 kcal
