Starch molecules are too large to pass through cell membranes and be utilized for energy in the body, whereas glucose is a simple sugar that can be readily absorbed and used for cellular processes. Therefore, starch would not be an effective substitute for glucose in saline solutions intended for medical purposes.
What else can I help you with?
1 Why are starch and glycogen useful as energy storage molecules while cellulose is useful for structure and support 2 Why cant humans break down cellulose?
Starch and glycogen are useful as energy storage molecules because they are composed of glucose monomers linked in a way that allows for easy hydrolysis, releasing glucose for energy when needed. In contrast, cellulose has a rigid structure due to its β-glucose linkages, making it ideal for providing structural support in plant cell walls. Humans cannot break down cellulose because we lack the enzyme cellulase, which is necessary to hydrolyze the β-glycosidic bonds between the glucose units in cellulose. As a result, cellulose passes through the digestive system undigested, contributing to dietary fiber instead.
Why are starch and glycogen useful as energy storage molecules while cellulose is useful for structure and support 2 Why cant humans break down cellulose?
Starch and glycogen are useful as energy storage molecules because they are made up of glucose units linked in a way that allows for easy breakdown and release of energy when needed. In contrast, cellulose provides structural support due to its rigid, linear chains of glucose linked by β-1,4-glycosidic bonds, which form strong fibers. Humans cannot break down cellulose because we lack the necessary enzyme, cellulase, to hydrolyze these specific bonds, rendering cellulose indigestible.
What system gets glucose into the blood?
the system that gets glucose into the blood is digestive system this question came up on my science homework and i am in year 8: this is the question: oh sorry i seriously cant be bothered
Why cant salt water be used to water crops?
It is not wise to irrigate crops using seawater. Sea water is very saline and it can kill the plants after a period of prolonged usage.
Which two factors of the molecule determine whether or not it can cross the membrane?
size and shape. cell membranes are selectively permeable, so only some molecules can get through. (i.e. water can go through, but starch cant) Polarity and size.
Can glucose enter the membrane?
yes it can, but other sugars that are more complex like cellulose or starch cant
Why cant plants produce sugar over night?
In the the night time there is no sun, hence no light. During the day a plant will use chloroplasts to make glucose, which is then stored as plant starch. When there is no sun for an extended period of time a plant can get energy from tubers. A tuber is a modified plant structure, under ground, where it can store excess glucose. (sugar is basically the same as glucose)
Is glucose c better for you than sugar?
Well glucose IS a type of sugar, so you really cant answer that question.
How fast can you run iv 0.25 percent saline?
Usually you cant run 0.25% saline at any rate since its extremely hypotonic so you need to add some dextrose to increase the tonicity
What is the relationship of starch production to light exposure?
There is no sun so photosynthsis cant be performed.
Can you digest starch?
Pepsin does not digest. It breaks down proteins into amino acids. Pepsin cannot break down starch. This is probably because the pH of starch is higher than the optimum pH of Pepsin.
How do you produce Synthetic glucose from air water light and oxygen?
you cant
Can someone with glucose intolerance have sugar alcohol?
Glucose is sugar ... Intolerance means your body cant handle it ... So ima have to say ... NO ...
Why cant glucose be able to move across a cell membrane by simple diffusion?
Glucose is a large and polar molecule, which makes it difficult to pass through the hydrophobic interior of the cell membrane. As a result, glucose requires specific transporter proteins to facilitate its movement across the membrane.
Can you use mint sauce instead of fresh mint?
no you cant
What food group do onions go into?
Vegetable but if your talking about protein and sugar and starch and stuff then I am afraid I cant help you hope it helps :)
How much glucose makes 1 gram sugar?
Glucose is, actually, a simple aldosic monosaccharide found in plants. Table sugar is also called sucrose and sucrose is made up of two glucose molecules.
