What process drives molecules across a membrane against a concentration gradient?
Active transport is the process that drives molecules across a membrane against a concentration gradient, requiring energy input in the form of ATP. This process allows cells to accumulate substances they need in higher concentrations than their surroundings.
Which process allows ions to move across a semipermeable membrane where the concentration of ions is low to where their concentration is even higher?

The process that allows a message to be carried across a membrane?
The process that allows a message to be carried across a membrane is called facilitated diffusion or active transport, depending on the type of message and the energy required. Facilitated diffusion involves the movement of molecules across a membrane with the help of transport proteins, while active transport uses energy to move molecules against their concentration gradient.
What type of molecules embebbed in the plasma membrane allows molecules to pass through the membrane by active or passive transport?
proteins
What is a description of endocytosis with active transport?
Endocytosis with active transport involves the process of cells taking in large molecules or particles through the cell membrane using energy from ATP. This form of endocytosis allows cells to selectively uptake specific substances from their environment by binding them to specific receptor proteins on the membrane. The energy required for this process ensures that only necessary substances are taken in by the cell.
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.

Which process is responsible for moving cellular wastes across the cell membrane?
The process for moving cellular wastes across the cell membrane is known as active transport. Active transport is a source of energy that allows molecules to move from low concentrations to high concentrations, and provides the needed boost to move the molecules uphill.
What is a description of endocytosis with active transport?

The energy required for this process ensures that only necessary substances are taken in by the cell.
How does active transport work to move molecules across the cell membrane?
Active transport is a process in which cells use energy to move molecules across the cell membrane against their concentration gradient. This is done by using specialized proteins called transporters that pump the molecules across the membrane. The energy required for this process is usually provided by ATP, the cell's energy currency. This allows the cell to maintain the proper balance of molecules inside and outside the cell.
Is the cell membrane selectibely permeable?
Yes. The cell membrane allows some materials to be let in, while keeping others out. This is done by passive or active transport.
What is the movement across a membrane with the help of ATP?
Active transport is the movement of molecules across a membrane with the help of ATP, which provides the energy needed for the transport process. This allows substances to move against their concentration gradient, from an area of lower concentration to an area of higher concentration.
