Active transport (or active uptake, as we learnt it ) is moving against the concentration gradient. This requires energy which is why the oxygen is needed (the oxygen producing energy through respiration). It is affected by the concentration of oxygen because the more oxygen, the more energy produced, the faster the process occurs. Diffusion is not affected by the concentration of oxygen because it does not require energy to occur.

Active transport does not directly require oxygen. It is a process that uses cellular energy, usually in the form of ATP, to move molecules against their concentration gradient across a cell membrane. Cells generate ATP through processes like cellular respiration, which does require oxygen.

∙ 12y agoif there is no oxygen then there is no energy and as we know that the active transport needs energy to be able to transport the substances to the cell,
therefore, no oxygen= no active transport!
hope it helps:)

∙ 13y agono, but it requires energy. passive transport doesnt require energy.

Is an example of active transport?
An example of active transport is sugar molecules going into a cell. It cannot pass right through like water and oxygen so it uses active transport.Diffusion
What is it called when sugars pass across the membrane that requires the use of energy?
active transport
Exocytosis active or passive?
active
How do you use active transport in a sentence?
Cells use active transport to pump nutrients into the cell against their concentration gradient.
What prevents active transport taking place?
Believe it or not, cyanide kills us by inhibiting active transport, to such an extent that substances can no longer be transferred across cell membranes. This is one example of a substance that stops the process of active transport dead in its tracks.
Does diffusion and active transport use oxygen?
Diffusion does not require energy and can occur without the need for oxygen. Active transport, on the other hand, requires energy in the form of ATP and does not directly involve the use of oxygen, although oxygen is essential for producing ATP through cellular respiration.
What is a process that releases energy when oxygen is insufficent?
Active Transport..........
What processes does not use ATP muscle contraction active transport heat production diffusion of oxygen cytoplasmic?
Diffusion of cytoplasmic oxygen.
How is facilitated transport different from active transport?
Facilated transport does not need to use energy but active transport does.
What effect does lack of oxygen have on active transport?
Lack of oxygen impairs aerobic metabolism, which is needed to produce the ATP required for active transport processes. This can lead to a decrease in the efficiency and effectiveness of active transport mechanisms, ultimately affecting the ability of cells to maintain ion gradients and transport molecules across membranes.
What 2 transport processes use carrier proteins?
Two transport processes that use carrier proteins are facilitated diffusion and active transport. In facilitated diffusion, carrier proteins help move molecules across the cell membrane down their concentration gradient, while in active transport, carrier proteins help move molecules against their concentration gradient by using energy.

If the substance entering the cell was in higher concentration inside the cell then outside the cell what type of transport would be required?
It would be active transport, a process which requires a cell to use its own energy (unlike passive transport).
Exocytosis active or passive?
active
What does active transport require the use of?
Energy
What is the process that requires the use of energy to move materials across a membrane?
Active transport is the process that requires the use of energy to move materials across a membrane. This process involves the movement of molecules against their concentration gradient, requiring energy input from the cell.
