The graphs illustrate the rate at which sugars are taken up by a culture of animal cells under various conditions. How are the sugars taken up by the cells when air is bubbled through the culture?
- A3-carbon sugar: active transport; 6-carbon sugar: active transport
- B3-carbon sugar: active transport; 6-carbon sugar: diffusion
- C3-carbon sugar: diffusion; 6-carbon sugar: active transport
- D3-carbon sugar: diffusion; 6-carbon sugar: diffusion
