Question 10 options: 1) both are polysaccharides 2) glycogen is from animals, starch is from plants 3) starch provides bulk and can't be broken down by the human body 4) starch is an energy storage molecule, glycogen is an immediate energy usage molecule
glycogen is from animals, starch is from plants

phosphate
Which one of the following statements about monosaccharides is FALSE? Question 3 options: 1) Monosaccharides may combine to form polysaccharides. 2) Monosaccharides form polysaccharides in the body primarily in the linear form. 3) Monosaccharides form polysaccharides in the body that can be stored in the liver. 4) Monosaccharides dissolve in water.
Monosaccharides for polysaccharides in the body primarily in the linear form
Which of the following statements are correct? 1 - Glucose and fructose need to be processed by the liver before entering other body cells. 2 - Glucose can enter nearly every cell of the body. 3 - High fructose corn syrup is 45% fructose and 55% glucose. 4 - High fructose corn syrup may increase the number of triglycerides found in the blood.
glucose can enter nearly every cell of the body, high fructose corn syrup may increase the number of triglycerides found in the blood (2 and 4)
Which two monosaccharides make up sucrose? Question 1 options: 1) fructose and galactose 2) glucose and fructose 3) glucose and galactose 4) glucose and glucose
gluctose and fructose
Amylopectin is to faster digestion as _________ is to faster rise of blood sugar. Question 18 options: 1) amylose 2) glycogen 3) cellulose 4) monosaccharides
glycogen
Cellulose Question 11 options: 1) is a disaccharide 2) is not broken down in the human body due to lack of the proper digestive enzymes 3) is not broken down in the human body due to the lack of storage capabilities 4) all of the above are true statements about cellulose
is not broken down in the body due to lack of the proper digestive enzymes
Glucose Question 8 options: 1) is an isomer with fructose and maltose 2) is the major nutrient for most cells of the body 3) is regulated by the Nervous system 4) is a 5-carbon sugar and a monosaccharide
is the major nutrient for most cells of the body
Which one of the following statements about polysaccharides is true? 1 - Polysaccharides are broken down by hydrolysis reactions. 2 - Polysaccharides are long chains of monosaccharides. 3 - Polysaccharides are only considered complex carbohydrates when they are branched. 4 - Polysaccharides are the products of a process called gluconeogenesis. 5 - Starch is an example of a digestible polysaccharide in humans.
polysaccharides are broken down by hydrolysis reactions, polysaccharides are long chains of monosaccharides, starch is an example of a digestible polysaccharide in humans. (1,2,5)
Why can't the human body breakdown cellulose? Question 17 options: 1) The human body lacks the enzymes to digest cellulose. 2) Cellulose contains fructose, which is difficult to use in metabolic pathways. 3) Cellulose is insoluble in water so it cannot be broken down 4) The bond configuration between glucose molecules is different in cellulose than it is in glycogen. 5) all the above
the human body lacks the enzyme to digest cellulose, the bond configuration between glucose molecules in different in cellulose than it is in glycogen (1 and 4)
Which of the following will occur if a person doesn't have the enzyme lactase? 1 - Lactose will be absorbed in the large intestine. 2 - Water will enter the lumen of the large intestine by osmosis. 3 - Lactose will pass through the small intestine and enter the large intestine 4 - Lactose will be broken down into two galactose molecules. 5 - The person will experience symptoms of abdominal bloating, cramps and diarrhea.
water will enter the lumen of the large intestine by osmosis, lactose will pass through the small intestine and enter the large intestine, the person will experience symptoms of abdominal bloating, cramps, and diarrhea. (2,3,5)
