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.
What else can I help you with?
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?
Active transport is the movement of a substance across a cell membrane from low to high concentration with the help of energy.
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 is it called when sugars pass across the membrane that requires the use of energy?
active transport
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 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.
What processes can take place in a root hair cell when oxygen is not available?
active transport and osmosis
