|
In the diagram shown which processes are represented by letters A and B? |
A—respiration; B—photosynthesis |
|
A baker activates yeast cells with hot water, and adds sugar as their source of food. As the yeast begin their metabolic processes, the bowl it is in is covered with plastic so that no oxygen can get to them. At this point, the yeast will __ |
perform anaerobic respiration in the absence of oxygen
|
|

The cellular process known as the sodium-potassium pump was discovered in the 1950s by Jens Christian Skou, a Danish scientist.
