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.
What else can I help you with?
How does facilitated transport differ from active transport in terms of the energy requirements and mechanisms involved in moving molecules across a cell membrane?
Facilitated transport and active transport are two ways molecules can move across a cell membrane. Facilitated transport does not require energy from the cell, while active transport does require energy in the form of ATP. Facilitated transport uses carrier proteins to help molecules move across the membrane, while active transport uses pumps to move molecules against their concentration gradient.
Which type of membrane transport process uses ATP as a source of energy?
Active transport processes use ATP as a source of energy to move molecules against their concentration gradient across a cell membrane. This process requires specific transport proteins, such as ion pumps, to actively transport molecules across the membrane.
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.
How are facilitated diffusion and active transport different in terms of their mechanisms of transporting molecules across the cell membrane?
Facilitated diffusion uses transport proteins to move molecules across the cell membrane with the concentration gradient, while active transport requires energy to move molecules against the concentration gradient.
Diffusion osmosis active transport all of these are methods by which a cell?
Diffusion, osmosis, and active transport are methods by which a cell can move molecules across its membrane. Diffusion is the passive movement of molecules from an area of high concentration to low concentration. Osmosis is the diffusion of water molecules across a selectively permeable membrane. Active transport requires energy to move molecules against their concentration gradient.
What ways of moving molecules across a membrane requires energy?
Active transport requires energy to move molecules across a membrane against their concentration gradient. This process is facilitated by specific carrier proteins embedded in the membrane that use energy, usually in the form of ATP, to transport molecules.
What is it called when molecules uses energy to move across a semipermeable membrane?
Active transport

Which process requires energy to bring molecules across the cell membrane?
Active transport requires energy to move molecules across the cell membrane against their concentration gradient. This process is carried out by specific proteins called pumps that utilize cellular energy in the form of ATP to transport molecules.
Diffusion osmosis active transport all of these are methods by which a cell?
Diffusion, osmosis, and active transport are methods by which a cell can move molecules across its membrane. Diffusion is the passive movement of molecules from an area of high concentration to low concentration. Osmosis is the diffusion of water molecules across a selectively permeable membrane. Active transport requires energy to move molecules against their concentration gradient.
Is diffusion of molecules across the cell membrane the most complex type of active?
Diffusion of molecules across the cell membrane is actually a passive process, not active. Active transport, which requires energy in the form of ATP, is a more complex process as it moves molecules against their concentration gradient.
When a cell expands energy to move molecules or ions across membrane the process is known as?
Active transport. This process requires energy, usually in the form of ATP, to move molecules or ions against their concentration gradient across a cell membrane.
What assists the movement of polar molecules across the membrane A. Passive Transport B. Active Transport?
Polar molecules must pass through the membrane via active transport. This is because the cellular membrane is mostly nonpolar, and polar and nonpolar molecules repel each other. Only nonpolar molecule (i.e. hormones) can pass through the membrane without active transportation.
What is the difference between active and facilitated transport in cellular processes?
Active transport requires energy to move molecules across the cell membrane, while facilitated transport uses carrier proteins to help molecules pass through the membrane without energy.
