What else can I help you with?
What is used to move a substance through a membrane in active transport?
Electrochemical gradient is used to move substances through a membrane in active transport.
Which processes are active transport of substances in and out of the cell?
cell membrane
Is active transport the only way substances can cross the intestinal membranes?
Diffusion too.
What is the name of the membrane that allows the movement of water and substances to move through the process of active transport and passive transport?
The cell membrane, also known as the plasma membrane, is responsible for regulating the movement of water and substances through processes like active transport and passive transport. It acts as a selectively permeable barrier, allowing certain molecules to pass through while blocking others.
What occurs if substances are too large to pass through the cell membrane by active or passive transport?
passive transport
Are carrier proteins active or passive transport?
Carrier proteins facilitate active transport by moving molecules or ions across a cell membrane against their concentration gradient. They require energy in the form of ATP to transport substances across the membrane.
In active transport carrier proteins do what?
They help transfer substances from the outside of the cell membrane to the inside.
The use of energy to move substances across a cell membrane describes?
Active transport, which requires energy in the form of ATP to move substances against their concentration gradient across a cell membrane. This process involves specific protein pumps that bind to the molecule being transported, consuming ATP to change conformation and move the molecule across the membrane.
When do cells do active transport?
When transporting substances from low to high concentration, or when transporting substances too large to pass through the membrane without assistance from a transport protein.
The movement of substances across the cell membrane that requires the cell to use energy?
It's called active transport. When talking about the cell, it is usually bigger substances that use passages in the cell membrane to access the inner part of the cell, and they need energy to get there. The opposite; passive transport or diffusion, is the movement of dissolved materials through a cell membrane without the use of cellular energy. THis happens with smaller substances.
Does active transport get substances across a cell membrane?
Yes, active transport is a process that uses energy to move substances across a cell membrane against their concentration gradient. This enables the cell to accumulate certain molecules or ions inside the cell or remove them from the cell.
What is the process by which substances are moved through the cell membrane by a carrier molecule?
facilitated diffusion or active transport
