Passive transport processes, such as simple diffusion and facilitated diffusion, do not require energy input from the cell. These processes rely on the movement of molecules along a concentration gradient, from an area of high concentration to low concentration.
facilitated diffusion
The passive ones, like diffusion
active transport
Yes, engulfing a particle of food by an amoeba requires energy as it involves the process of endocytosis where the cell membrane surrounds and engulfs the food particle. This process requires ATP, the cell's energy currency, to power the necessary molecular machinery.
Aerobic respiration is the process that requires the presence of oxygen to release energy. During aerobic respiration, glucose is broken down in the presence of oxygen to produce ATP, which is the energy currency of the cell.
Diffusion is when small molecules move in and out of a cell. This process requires no energy aka passive transport!(:
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.
Passive transport. This process allows molecules to move across the cell membrane without the use of energy. It includes simple diffusion, facilitated diffusion, and osmosis.
Active transport requires energy to move a molecule.
Active transport is the process by which a cell uses energy to move molecules or ions across a cell membrane against their concentration gradient. This process requires the use of ATP energy to pump substances from an area of low concentration to an area of high concentration.
Endocytosis is the process that uses transport vesicles to take in molecules for the cell. It requires energy in the form of ATP to carry out the engulfing of substances by the cell membrane and their transport into the cytoplasm.
