Is exocytosis considered a form of passive transport?
No, exocytosis is not considered a form of passive transport. It is an active process where cells expel materials by fusing vesicles with the cell membrane.
Why is the process of etc considered an aerobic process?
The process of etc, or electron transport chain, is considered an aerobic process because it requires oxygen to function. Oxygen is the final electron acceptor in the electron transport chain, allowing for the production of ATP, the cell's main energy source. Without oxygen, the electron transport chain cannot proceed, making it dependent on aerobic conditions.
The energy requiring process that moves molecules and ions across a membrane from low concentrations to high is called?
Idoes active transport always require transport proteins during the process
Why is facilitated diffusion not considered an active transport process?
Facilitated diffusion is not considered an active transport process because it does not require energy input from the cell. Instead, it relies on the assistance of transport proteins to move molecules across the cell membrane, following their concentration gradient. Active transport, on the other hand, requires energy to move molecules against their concentration gradient.
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 process moves materials through a cell from areas of concentrations to areas of high concentration?
active transport
What process drives molecules across a membrane against a concentration gradient?
Active transport is the process that drives molecules across a membrane against a concentration gradient, requiring energy input in the form of ATP. This process allows cells to accumulate substances they need in higher concentrations than their surroundings.

Why does active transport allow cells to accumulate substances in high concentrations where as passive means of transport do not?
Active transport uses energy from ATP to carry substances such as glucose to areas where it is required through the use of transport proteins. Whereas, facilitated diffusion is a passive process by which molecules move from an area of high concentration to an area of low concentration and it also depends on kinetic energy. Meaning that the distribution of molecules by facilitated diffusion will be random, whereas, active transport will have control over the direction of the concentration gradient.
What is the main process by which nitrate ions are absorbed Give a reason for your answer?
The main process by which nitrate ions are absorbed in plants is through active transport. This is because nitrate ions are usually present in low concentrations in the soil, and active transport allows plants to move these ions against their concentration gradient by using energy from ATP to uptake them efficiently.
When active transport used to move molecules what is required?
Active transport requires energy, typically derived from ATP, to move molecules against their concentration gradient. This process involves specific transport proteins or pumps in the cell membrane that facilitate the movement of substances into or out of the cell. Unlike passive transport, which relies on concentration differences, active transport allows cells to maintain essential concentrations of ions and nutrients necessary for various cellular functions.
Is exocytosis a passive or active process in cellular transport?
Exocytosis is an active process in cellular transport.
What is passive transport diffusion?
When there is a solution on either side of a barrier (membrane for example) withing a cell, the concentrations of said solution will be different on either side of the barrier. Concentrations do not like to be different and will move from high to low until they are equal. For example, there are sodium ions on either side of a cell membrane. the concentration is higher inside, so to make the concentrations equal, some salt ions move through transmembrane proteins from the inside of the cell to the outside. it's called passive because it doesn't use any energy
