1. Sugar (sucrose) cannot penetrate the cells and cannot be absorbed in blood because this disaccharide molecule is too big.
2. After the degradation of the disaccharide to monosaccharides (fructose, glucose, etc.) with the help of the enzyme sucrase these monosaccharides are easily absorbed in blood.
3. The monosaccharides molecules can penetrate by diffusion.
What else can I help you with?
Water soluble molecules often enter or exit a cell in what process?
Water soluble molecules often enter or exit a cell through a process called facilitated diffusion. This process involves the movement of molecules across the cell membrane with the help of specific protein channels or carriers.
What provides the cell with energy from sugar?
The process of cellular respiration breaks down sugar molecules to release energy. This process occurs in the mitochondria of the cell, where sugar molecules are oxidized to produce ATP, the cell's primary energy source.
Must sugar dissolve in blood to enter cells?
No, sugar enters cells through facilitative diffusion, a process that does not require it to dissolve in blood. Cells use specialized transport proteins to move sugar molecules from the blood into the cell.
What is the process by which large molecules enter a cell through pouches in the membrane?
The process by which large molecules enter a cell through pouches in the membrane is called endocytosis. During endocytosis, the cell membrane forms a pouch around the molecule, encloses it, and brings it into the cell as a vesicle. This allows the cell to take in larger molecules that would not be able to pass through the membrane on their own.
Does passive transport require sugar?
Passive transport does not require sugar. Passive transport is a process by which molecules move across a cell membrane without the input of energy, such as diffusion or osmosis. Sugar molecules can be transported passively, but the process itself does not depend on sugar.
What is the process by which molecules of sugar pass through an animal cell membrane to replenish the cell's lack of sugar is?
The process by which molecules of sugar pass through an animal cell membrane is called facilitated diffusion. In this process, sugar molecules move across the cell membrane with the help of specific transport proteins. These transport proteins create channels for the sugar molecules to pass through, allowing them to replenish the cell's supply of sugar.
Sugar molecules can enter cells through the process of what?
Sugar molecules can enter cells through the process of facilitated diffusion or active transport. Facilitated diffusion involves the use of transporter proteins to move sugars across the cell membrane, while active transport requires energy to move sugars against a concentration gradient into the cell.

Which organelle breaks down sugar molecules that supply energy to the cell?
mitochondria
Does passive transport require sugar?
Passive transport does not require sugar. Passive transport is a process by which molecules move across a cell membrane without the input of energy, such as diffusion or osmosis. Sugar molecules can be transported passively, but the process itself does not depend on sugar.
What process is used to move sugar molecules across a cell membrane?
The process used to move sugar molecules across a cell membrane is called facilitated diffusion. This process involves the use of transport proteins in the cell membrane to help facilitate the movement of sugar molecules from an area of higher concentration to an area of lower concentration, without requiring energy input from the cell.
As the concentration of molecules outside a cell increases more molecules will enter the cell?
Yes, this process is known as osmosis. Water moves from an area of low solute concentration (outside the cell) to an area of high solute concentration (inside the cell) to balance the concentration levels. This causes more molecules to enter the cell as the concentration difference increases.
In which process in which process this is so you molecules does the cell use a vesicles to move molecules into the cell?
cells
What chemical acts like a key to a cell?
hormones such as insulin opens up channel proteins which are like doors to a cell. Channel proteins allow larger molecules, such as sugar, to enter the cell.
