What else can I help you with?
What is it called when molecules uses energy to move across a semipermeable membrane?
Active transport
What is net movement of substances across plasma membrane without additional energy?
Diffusion. With the need of energy, it would be called active transport.
What is the name of the process of how things get in and out of the cell?
The process by which substances enter and exit the cell is called cellular transport. It primarily occurs through two main mechanisms: passive transport, which does not require energy, and active transport, which requires energy expenditure by the cell. Examples of passive transport include diffusion and osmosis, while examples of active transport include endocytosis and exocytosis.
What separates active transport from passive transport?
Active transport is when a cell needs to use energy in or to let substances pass in through or out or its cell membrane or cell wall. Passive transport requires to energy at all making substances like water easy to let pass through.
What is the active transport in a cell call?
It can be called phagocytosis when referring to food and it can be called pinocytosis when referring to fluid, but most of the times it's called active transport. It can also be called exocytosis and endocytosis.
What is the transport of substances from outside to the inside of a cell by a vesicle called?
Vesicular active transport
What is the transport of a substances from the outside to the inside of a cell by a vesicles called?
Vesicular active transport
What is it called when molecules uses energy to move across a semipermeable membrane?
Active transport
What is the Method of movement that requires the expenditure of ATP molecules is?
The movement that requires the expenditure of ATP molecules is called active transport. In active transport, cells use ATP to move molecules or ions against their concentration gradient, ensuring that specific substances are taken up or expelled from the cell as needed. This process is essential for maintaining cellular functions and homeostasis.
The transport of a substance across the cell membrane against its concentration gradient is called what?
The transport of a substance across the cell membrane against its concentration gradient is called active transport.
What is it called when materials move from lower to higher concentration?
Specifically Diffusion, but it is also active transport
What is net movement of substances across plasma membrane without additional energy?
Diffusion. With the need of energy, it would be called active transport.
What proceeds against a concentration gradient?
Molecules can move against concentration gradient by a movement called active transport. Molecules move from an area of low concentration to an area of high concentration by using chemical energy called ATP or an electrochemical gradient--either way, it uses cellular energy.
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.
How does active transport work against the concentration gradient to move substances across a cell membrane?
Active transport is a process in which cells use energy to move substances against their concentration gradient, from an area of low concentration to an area of high concentration, across the cell membrane. This is achieved by using specialized proteins called pumps that actively transport the substances across the membrane, requiring energy in the form of ATP.
What is the name of the process of how things get in and out of the cell?
The process by which substances enter and exit the cell is called cellular transport. It primarily occurs through two main mechanisms: passive transport, which does not require energy, and active transport, which requires energy expenditure by the cell. Examples of passive transport include diffusion and osmosis, while examples of active transport include endocytosis and exocytosis.
What functions do carrier proteins perform in active transport?
Carrier proteins in active transport actively pump molecules or ions against their concentration gradient across a cell membrane using energy from ATP. They allow specific substances to be moved across the membrane in a controlled manner, helping to maintain cellular homeostasis and regulate cell function.
