What else can I help you with?
This transport process moves substances agaisnt a concentrating gradient and requires energy?
active transport
What must a cell expand during active transport to accomplish movement of a substance?
During active transport, a cell must expand its energy in the form of ATP to pump molecules or ions across a membrane against their concentration gradient. This process requires energy to create a concentration gradient and move substances from low to high concentration.
What substances are transported by active transport?
Substances that are transported by active transport include ions such as sodium, potassium, calcium, and hydrogen, as well as certain organic molecules and nutrients like glucose and amino acids. Active transport requires energy to move substances against their concentration gradient, typically utilizing ATP as a source of energy.
Is it true that active transport differs from passive transport in that it does not require an input of energy?
No, active transport requires an input of energy, usually in the form of adenosine triphosphate (ATP), to move substances against their concentration gradient. Passive transport, on the other hand, does not require energy and relies on the natural movement of substances down their concentration gradient.
Is active transport the only way substances can cross the intestinal membranes?
Diffusion too.
Is used during active transport but not passive transport?
ATP (adenosine triphosphate) is used during active transport but not passive transport. Active transport requires energy to move substances against their concentration gradient, while passive transport relies on diffusion to move substances down their concentration gradient without the need for energy.
Does active transport move substances against the concentration gradient?
Yes, active transport moves substances against the concentration gradient.
Does active transport move substances against their concentration gradient?
Yes, active transport moves substances against their concentration gradient.
What is active transport across the cell?
Active transport simply means the transport of substances against the concentration gradient.In this transport,ATP is utilised.
What is the purpose of active transport?
Active transport expends energy to move substances against a concentration gradient.
How do carrier proteins recognize substances to transport in active transport?
substance to pass
What is the transport of substances from the outside to the inside of a cell by a vesicle?
Vesicular active transport
How do carrier protein recognize substances to transport in active transport?
substance to pass
Are osmotically active substances simple diffusion or active transport?
simple diffusion.
How does active transport help the body?
active transport helps the body because it is the movement of substances against the concentration gradient.
What is a major difference between facilitate diffusion and active transport?
Active transport moves substances against the concentration gradient.
What is the transport of substances from outside to the inside of a cell by a vesicle called?
Vesicular active transport
