How does ATP release energy that can be used by living cells?

Why can’t an aerobic bacterium produce as much energy as an animal cell can produce from a gram of sugar?

Four small bags are filled with a 10% starch solution. The membrane of each bag contains microscopic pores large enough to let smaller water molecules cross but too small for the larger starch molecules to cross. Each bag is placed in a separate beaker as follows:Bag 1 is placed in distilled water containing no starch (0% starch).Bag 2 is placed in a solution of distilled water and 5% starch.Bag 3 is placed in a solution of distilled water and 10% starch.Bag 4 is placed in a solution of distilled water and 50% starch.The bags are weighed initially and at regular intervals for a specific period of time. Some bags saw a change in weight, and some did not. Answer the following questions based on the expected outcomes of this experiment.a. Which bag should weigh approximately the same at the end of the experiment as it did at the beginning of the experiment?b. Which bag is expected to be the heaviest at the end of the experiment?

Both the volume and the surface area for three different cells were measured. These values are listed in the following table: ​ Volume Surface Area Cell 1 9.3 μm3 26.5 μm2 Cell 2 12.2 μm3 37.1 μm2 Cell 3 17.6 μm3 40.6 μm2 Using data from the table above, select the best explanation for why that cell will be able to eliminate waste most efficiently?

Use the following information to answer the questions.A part of an mRNA molecule with the following sequence is being read by a ribosome: 5′-CCG-ACG-3′ (mRNA). The following charged transfer RNA molecules (with their anticodons shown in the 3′ to 5′ direction) are available. Two of them can correctly match the mRNA so that a dipeptide can form. tRNA Anticodon Amino Acid GGCCGUUGCCCGACGCGG ProlineAlanineThreonineGlycineCysteineAlanine Which of the following dipeptides will form from this mRNA?

An unknown organism was inoculated on MacConkey agar and a glucose sugar fermentation broth and incubated for 24 hours. The results of these inoculations are shown below. Based on the results observed, what can you determine about this organism?
