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 energy is used in active transport?
Active transport requires the input of energy in the form of ATP (adenosine triphosphate) to move molecules or ions against their concentration gradient across a cell membrane. This process is necessary for maintaining proper cellular function and regulating the internal environment of the cell.
What do electrons do in the electron transport chain?
In the electron transport chain, electrons move along a series of protein complexes, releasing energy that is used to pump protons across a membrane. This creates a proton gradient that drives the production of ATP, the cell's main energy source.
What source of energy is used in active transport?
Active transport uses energy in the form of adenosine triphosphate (ATP) to pump molecules against their concentration gradient across a cell membrane. ATP provides the necessary energy for the carrier proteins involved in active transport to move molecules from an area of low concentration to an area of high concentration.
The source of energy for the process of photosynthesis?
The source of energy for the process of photosynthesis is sunlight. Through a series of complex reactions, plants and other photosynthetic organisms convert light energy into chemical energy in the form of glucose. This process is essential for the production of oxygen and is at the foundation of the Earth's food chain.
Active transprort occurs when someting is used to move substances through a membrane?
Active transport is a process that requires energy to move molecules across a cell membrane against their concentration gradient. This process involves specific transport proteins that act as pumps to move molecules such as ions or other nutrients against the concentration gradient. ATP is typically required as an energy source for active transport to occur.
What is the source of the energy used in active transport?
The energy used in active transport is derived from ATP (adenosine triphosphate), which is produced through cellular respiration in the mitochondria of cells. ATP provides the necessary energy for the transport proteins to move molecules against their concentration gradient 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.
Is diffusiona type of passive transport or active transport?
Passive transport is where materials are transported across a membrane without the use of stored energy. Active transport is where materials are transported across a membrane using ATP, or another source of stored cellular energy. Diffusion is where solutes flow across a membrane in response to a concentration gradient, and requires no energy input to occur. Therefore, diffusion is a form of passive transport.
Transport chain series of proteins embedded in a membrane along which energized electrons are transported as electrons are passed from molecule energy is released?
The electron transport chain is a series of protein complexes embedded in the inner mitochondrial membrane. As electrons pass through this chain, energy is released and used to pump protons across the membrane, creating an electrochemical gradient. This gradient is then used by ATP synthase to generate ATP, the main energy source for cellular functions.
Which requires the use of energy to move a molecule across a cell membrane?
No. Water molecules can osmotically cross the cell membrane because they are small enough that their polarity does not matter. Then there are porins. Channels across the cell membrane that water molecules use.
What energy is used in active transport?
Active transport requires the input of energy in the form of ATP (adenosine triphosphate) to move molecules or ions against their concentration gradient across a cell membrane. This process is necessary for maintaining proper cellular function and regulating the internal environment of the cell.
Is energy used in active transport?
ATP is often used as the source of energy during active transport.
How does a large particle leave a cell by a active transport?
It requires energy, and a protein carrier molecule. The large particle binds to the protein carrier on the inside of the cell. It is then transported across the membrane as a result of a conformational change in the protein (think of it flipping), and then it is released on the outside of the cell. Again, this requires some source of energy.
What do electrons do in the electron transport chain?
In the electron transport chain, electrons move along a series of protein complexes, releasing energy that is used to pump protons across a membrane. This creates a proton gradient that drives the production of ATP, the cell's main energy source.
What is the energy source for co-transport?
The energy source for co-transport is typically the concentration gradient of one substance that is established by an active transport process. This concentration gradient drives the movement of another substance against its own concentration gradient through a symporter protein.
