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.
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

active
Cells use active transport to pump nutrients into the cell against their concentration gradient.
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.
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.

Diffusion of cytoplasmic oxygen.
Facilated transport does not need to use energy but active transport does.
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.

active transport
It would be active transport, a process which requires a cell to use its own energy (unlike passive transport).
active
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.
