What else can I help you with?
How is active transport different then then other types of cell transport?
active transport requires input of energy as it takes place aginst a gradient.
When would active transport be used by a cell?
Active transport is used when molecules are moved across a cell membrane against their concentration gradient, from a low to a high concentration.
where does active transport takes place which part of the cell?
Active transport takes place in the small intestine, where nutrients are absorbed from the intestine and into the bloodstream. More specifically, it is the structures known as villi that contain the protein receptors necessary for active transport to take place. The process also happens in the nephrons of the kidneys, where glucose and water/ions are selectively reabsorbed back into the bloodstream.
What prevents active transport taking place?
Believe it or not, cyanide kills us by inhibiting active transport, to such an extent that substances can no longer be transferred across cell membranes. This is one example of a substance that stops the process of active transport dead in its tracks.
What are two ways cell moves things by active transport?
passive transport and active transport.
How is active transport different then then other types of cell transport?
active transport requires input of energy as it takes place aginst a gradient.
If the substance entering the cell was in higher concentration inside the cell then outside the cell what type of transport would be required?
It would be active transport, a process which requires a cell to use its own energy (unlike passive transport).
Which type of transport could not occur if the cell was inhibited in the production of protein?
Active transport would not be able to occur if the cell was inhibited in the production of proteins. Active transport relies on specific proteins, such as pumps and carriers, to move molecules against their concentration gradient. Without these proteins, the cell would not be able to perform active transport.
What concentration does active transport take place in?
the phospholipid bilayer of a cell

What adaptation would increase the efficiency of active transport of carbohydrates from a plant cell?
Increasing the number of carrier proteins involved in active transport or increasing the surface area of the plasma membrane would enhance the efficiency of active transport of carbohydrates from a plant cell. Additionally, regulating the activity of enzymes involved in active transport could also improve the efficiency.
How would sugar entering a cell that already contains a high concentration of sugar get through a cell membrane into a cell?
It would be Active Transport.
