What are examples of monosaccharide?
Glucose and Fructose are examples of monosaccharides.
How do galactose, fructose, and glucose differ in terms of their chemical structures and metabolic pathways?
Galactose, fructose, and glucose are all monosaccharides, or simple sugars, but they differ in their chemical structures and metabolic pathways. Galactose and glucose have similar structures, while fructose has a different structure. In terms of metabolism, galactose and glucose are primarily metabolized in the liver through the same pathway, while fructose is metabolized differently in the liver and can have different effects on the body, such as contributing to fat accumulation.
What statement explains why oxygen molecules easily diffuse across a cell membrane which glucose molecules do not?
Glucose is too big to pass throught.
A molecule such as glucose must use a protein channel to cross through a cell membrane?
This is correct. Glucose, being a large molecule, requires a protein channel called a glucose transporter to facilitate its passage through the cell membrane. Glucose transporters assist in transporting glucose molecules across the hydrophobic lipid bilayer of the cell membrane.
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.
Which of these sugars are made by humans glucose fructose mannose starch vitamin c sucrose maltose lactose galactose?
Humans make glucose, fructose, and galactose, as these are monosaccharides that our bodies can produce. The others listed are not made by humans but are consumed through diet or supplementation.
What does galactose galactose and glucose make?
The monosaccharides galactose and glucose, when bonded together through a condensation reaction, form the disaccharide lactose.
How does glucose convert into glucose mannose and fructose?
Glucose can be converted into mannose through an epimerization reaction, specifically at the C2 position, which involves the enzyme mannose-6-phosphate isomerase. This process converts glucose-6-phosphate into mannose-6-phosphate, which can subsequently be dephosphorylated to yield mannose. Fructose is formed from glucose through a series of enzymatic reactions involving the conversion of glucose to glucose-6-phosphate, then to fructose-1,6-bisphosphate via phosphofructokinase, and finally to fructose through the action of aldolase. These conversions are part of the broader metabolic pathways that utilize glucose for energy production and carbohydrate metabolism.
What two monosaccharides make up milk sugar?
The 2 mono saccharides that make up lactose are glucose and galactose. Glucose is basically sugar in its most basic form. It is made by plants through photosynthesis.
What is the enzyme that convert galactose into glucose 1 phosphate?
The enzyme that converts galactose into glucose 1-phosphate is galactokinase. This enzyme phosphorylates galactose to form galactose 1-phosphate, which can then be converted into glucose 1-phosphate through further metabolic pathways.
How do sugar glucose molecules able to pass through the cell membrane?
facilitated diffusion - a solute binds to a specific transporter on one side of the membrane and is released on the other side after the transporter undergoes a conformational change. includes glucose,urea,fructose,galactose,and some vitamins.
What is a galactose is converted to after absorption in the liver?
After absorption in the liver, galactose is converted to glucose-1-phosphate through a series of enzymatic reactions. This conversion is part of the galactose metabolism pathway, where galactose is first phosphorylated to galactose-1-phosphate before being transformed into glucose-6-phosphate, which can then enter glycolysis or be used for glycogen synthesis. Ultimately, this process allows galactose to be utilized as an energy source similar to glucose.
What are the products of hydrolysis of maltose?
When a molecule of lactose is hydrolyzed the monomers that had linked together to form lactose will be pulled away from each other through the addition of lactose. Lactose is made from GLUCOSE AND GALACTOSE, henceforth these two monomers will emerge through the hydrolysis of lactose. Hope this helps...
Why does glucose have a higher energy of confirmation than mannose?
Glucose has a higher energy of confirmation than mannose because of the difference in their molecular structures. Glucose has a more stable structure due to its exocyclic oxygen on C1, which leads to a lower energy confirmation. In contrast, mannose has a higher energy confirmation due to the steric hindrance between the C2 and C3 hydroxyl groups.

Why absorption rate of galactose is more than glucose?
The absorption rate of galactose is higher than glucose because galactose is transported into enterocytes by a secondary active transport mechanism that involves a carrier protein, which allows for faster absorption. In contrast, glucose is primarily absorbed through facilitated diffusion, which is a slower process.
