Question

a scientist studies cultures of four different types of cells undergoing cellular respiration and determines the average number of atp molecules produced per cell, per molecule of glucose consumed. another scientist suggests that some of the cultures might be of a bacterium called clostridium, which is an obligate anaerobe (it cannot undergo aerobic respiration). which cell(s) could possibly be clostridium? cell w cell x cell y cell z average number of atp produced trial 1 36 2 34 2 trial 2 36 2 34 2 trial 3 35 2 34 2 trial 4 36 2 35 2 o w only o w and y o w, x, y, and z o x and z

Explanation:

Clostridium is an obligate anaerobe. Obligate anaerobes produce a relatively low amount of ATP compared to aerobic - respiring cells. Cells X and Z produce only 2 ATP on average, which is characteristic of anaerobic respiration. Cells W and Y produce much more ATP (average around 35 - 36), which suggests aerobic respiration. So, cells X and Z could be Clostridium.

Answer:

X and Z
