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.

JudyActive 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.

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.
