The correct answer is option E
The kingdom Protista includes large diversity of organisms ranging from flagellated cells to macroscopic organisms. It is sometime referred as Protoctista instead of Protista. Some of the ancient Protista’s have characteristics of animal and plant kingdom. For example Lichen is not a protist but it includes the characteristics of both Protista and Fungi. Likewise organisms such as algae, bacteria, ciliates have the features of Protist as all these are Eukaryotic cells. Since the formation of kingdom Protista many animals have been included and excluded from the kingdom. Even today red and brown algae are considered as protist
<span>Since oxygen is required in the electron transport chain the cell is unable to break down glucose past pyruvate. This means that both pyruvates and acetyl-CoA are unable to help produce further ATP. The cell is still able to break down the 5 glucose molecules using glycolysis however instead of producing pyruvate its final product is lactic acid. Since each glucose is can create 4 ATP (net 2 ATP) five glucose molecules would produce 20ATP net (10ATP).</span>
