Large molecules, such as glucose, are not able to pass through the cell membrane. Therefore proteins are needed to transport them across.

To perform active transport cells use?
atp and transport proteins. novanet.
Are transport proteins only in plant cells?
No, transport proteins are also in other organisms.
What substances used to help active transport occur within cells?
Transport Proteins
Do cells in villi uptake glucose by active transport?
yes but sometimes no
Why do cells need to use transport proteins function?
Some molecules are too large to pass through the cell membrane without transport proteins.
How does the gloucose get into the cells?
There are glucose transport proteins. Since there are fewer glucose particles in the cell (when compared to the fluid outside of cells), it is passive transport, which occurs naturally. The transport protein is necessary for the glucose to pass through the cell membrane.
To perform active transport cells use?
atp and transport proteins. novanet.
Are transport proteins only in plant cells?
No, transport proteins are also in other organisms.
Describe the role of carrier proteins during active transport?
they work as a catalysator for the transportation. They lower the nessesary energy for a transport to start. This can in many cases only be achieved by highly specifically adapted carriers, which in cells is mostly proteins.
What do cells use to perform active transport?
ATP and Transport Proteins
What are the Tubes in cells that transport proteins?
Endoplasmic Reticulum.
What is the process by which molecules such as glucose are moved into cells along their concentration gradient with the help of membrane bound carrier proteins called?
The process by which molecules such as glucose are moved into cells along their concentration gradient with the help of membrane bound carrier proteins is called facilitated diffusion. Facilitated transport is passive and does not directly require chemical energy from ATP.
How are glucose molecules moved into cell?
Glucose can move into cells by active or passive transport, in both cases membrane-spanning proteins are required. Active transport (SGLT) uses the concentration gradient of Sodium ions to move glucose against its concentration gradient. Passive transporters (GLUT) are only effective if the concentration of glucose in the cell is lower than outside the cell.
What substances used to help active transport occur within cells?
Transport Proteins
What type of transport supplies a cell with glucose?
thanks to: Bobama 08. question: what transport supplies a cell with glucose? answer: The passive transport supplies a cell with glucose. A passive transport is the diffusion of particles through the proteins. The particles move from an area of high concentration to an area of low concentration. The cell does not need to use any energy to make this happen. Whereas, an active transport is the movement of particles through proteins against the normal direction of diffusion. Particles are moved from an area of low concentration to an area of high concentration. The cell must use energy to make this happen. This energy comes from the molecule ATP, which stores energy in a form that cells can use. Therefore, the passive cell transport supplies a cell with glucose.
Why do cells to use transport proteins to function?
Some molecules are too large to pass through the cell membrane without transport proteins.
Do cells in villi uptake glucose by active transport?
