Pinky_delly asks:

what causes yeast to respire aerobically or how does yeast resoire aerobically. I have gotten a lab to show how yeast respires aerobically.

etutor answers:
Yeast respires anaerobically when it does not have enough oxygen to respire aerobically. Anaerobic respiration is less efficient (produces less energy) than aerobic, so it is only used as a sort of 'backup' when aerobic respiration can't happen.

thank u 4 the help. But check this part out. I did an experiment and when the oil was added to the yeast the oil began to rise, and the yeast rose afterwards. During the occasional rising of the yeast, bubble appeared in the lime juice. As the oil settled at the bottom of the test tube, and the yeast settled at the top.
Can u say why all of this occurred please?
