Active transport mechanisms, such as the sodium-potassium pump in cell membranes, require energy in the form of ATP to move substances against their concentration gradient. Endocytosis and exocytosis, which involve the uptake and release of large molecules or particles by cells, also require energy.
Passive transport does not require energy as it allows molecules to move across a membrane from an area of higher concentration to an area of lower concentration. Examples of passive transport include diffusion, osmosis, and facilitated diffusion.
Yes, engulfing requires energy because the amoeba must expend energy to rearrange its cytoplasm and membrane to surround and engulf the food particle. This process involves active transport mechanisms to move the engulfed material inside the cell.
Active transport requires energy to move molecules across a cell membrane, typically against a concentration gradient. This process is vital for maintaining proper internal conditions within a cell. Examples of active transport mechanisms include pumps and vesicular transport.
Yes, active transport requires the cell to expend energy in the form of ATP in order to move molecules against their concentration gradient. This process allows the cell to maintain proper concentrations of molecules inside and outside the cell.
Yes, clocks use energy to operate. This energy can come from batteries, electricity, or mechanical mechanisms like springs. Digital clocks typically require electricity, while analog clocks may use batteries or winding mechanisms to function.
Active transport mechanisms, such as sodium-potassium pumps, proton pumps, and endocytosis/exocytosis, require energy expenditure by the cell in the form of ATP. These processes involve the movement of substances against their concentration gradient, from an area of lower concentration to an area of higher concentration, which requires energy input.
Movement of substances into and out of cells include passive mechanisms that do not require cellular energy (diffusion, facilitated diffusion, osmosis, and filtration) and active mechanisms that use cellular energy (active transport, endocytosis,and exocytosis).
They do not require energy, which is often in the form of ATP.
Sugar is typically transported across a cell membrane using passive transport mechanisms like facilitated diffusion or simple diffusion. These processes do not require energy input from the cell. However, in some cases, active transport mechanisms such as the sodium-glucose cotransporter may be involved when sugars need to be transported against their concentration gradient, requiring energy.

Active Transport
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.
diffusion, facilitated diffusion, and osmosis
Passive transport mechanisms, such as diffusion and facilitated diffusion, do not require the cell to expend energy. These processes rely on the natural movement of molecules from an area of higher concentration to an area of lower concentration.
Passive transport mechanisms such as diffusion and osmosis do not require the breakdown of ATP, as they rely on the natural movement of molecules from an area of high concentration to low concentration. This process does not require energy input.
nothing, passive transport doesn't require energy
Polar molecules, ions, and large molecules like proteins typically require energy to cross the cell membrane because they cannot diffuse through the hydrophobic lipid bilayer. This process often involves the use of transport proteins or energy-dependent mechanisms such as active transport.
