Q

Mainly: Amylose and amylopectin

Large number of glucose molecules

20
Q

is manufactured in the leaves of plants from excess glucose produced during photosynthesis and serves the plant as a reserve food supply

21
Q

Stored in chloroplasts

22
Q

Most of the nutritional value of food comes from

23
Q

This stored form of glucose is made up of many connected glucose molecules.

It is found in greatest abundance in liver and muscle cells

24
Q

Many connected glucose

25
Normal blood glucose levels
70-100 mg/dl
26
where the extra glucose molecules are linked together to form glycogen
Glycogenesis
27
Glycogen stores in the liver assist in
Regulation sugar-dependent function of the entire body
28
Glycogen stores in the muscle assist in
Helps fuel and regulate physical activity, especially in high-intensity excessive and explosive movements
29
Glucose polymers
Cellulose
30
Found in all plant cell walls
Cellulose
31
resists digestion in the small intestine and reaches the colon largely intact, therefore, it does not provide energy
Dietary fiber
32
dissolves in water to form a gel-like substance
Soluble fiber
33
This process produces short-chain fatty acids, which support the health of the colon cells and regulate immune function
Fermentation.
34
soluble fiber can help lower blood cholesterol levels by
binding to cholesterol and aiding its excretion, and slows down the absorption of sugar, contributing to better blood sugar control
35
not dissolve in water and adds bulk to the stool
Insoluble fiber
36
is a way to rank carbohydrates 0-100 On how high the blood sugar rise after eat
Glycemic index
37
The higher the GI, the ___ the effect on blood sugar levels
greater
38
Foods low on the glycemic index (GI) scale are more __ digested and produce ___ ____ in blood sugar levels.
slowly gradual rises
39
Foods high on the glycemic index are ___ digested and absorbed, and therefore cause ___ fluctuations in blood sugar levels
rapidly large
40
Foods high in refined carbs and sugar are… digested and __ GI
digested more quickly and often have a high GI
41
foods high in protein, fat, or fiber typically have a ____ GI.
low GI
42
Foods that contain no carbs are ____________ GI and include meat, fish, poultry, nuts, seeds, herbs, spices, and oils.
not assigned a GI
43
Other factors that affect the GI of a food
ripeness, cooking method, type of sugar it contains, and amount of processing it has undergone
44
Foods that cause a fast rise in blood sugar also cause it
To fall sharply soon after eating.
45
Blood sugar spikes can cause
Lethargy and hunger That can lead to diabetes type 2
46
The release of insulin in short, sharp bursts causes stress to the ___ cells, which in the long run can lead to ____ and ____
β-cells, Insulin sensitivity and diabetes.
