Exam 4: The Cell

Which of the following is found in both eukaryotic and prokaryotic cells?

A form of diffusion in which the molecules pass through a protein instead of between the phospholipids is called ________.

________ are membrane proteins that help cells to stick to each other.

Which of the following steps in normal cellular respiration ends with formation of water?

Which of the following is a membranous organelle that chemically modifies and ships proteins to other organelles or out of the cell?

From which of these phases of cellular respiration does the cell get the most ATP?

Cilia and flagella are both made of ________.

You have a bacterial infection. Your immune system will be able to distinguish this foreign invader from other cells by ________.

________ is a metabolic process that creates ATP for the cell by the breakdown of glucose molecules. This process occurs in the cytoplasm.

Which of the following is true of both cilia and flagella?

The organelle known as the ________ makes phospholipids.

The movement of water through a selectively permeable membrane from areas of high concentration to areas of low concentration until equilibrium is reached can be described as ________.

If substantial lactic acid were found in a person's bloodstream, which type of glucose breakdown is occurring?

We know that from their mother's milk, infants gain proteins called antibodies that protect them from specific germs. We also know that proteins will eventually be broken down by a person's digestive system. How is it that these antibodies can get into the bloodstream of the breast-feeding infant intact? Use only the information from this chapter.

If natural selection would select against organisms with a nucleus, which one of the following organisms would survive and evolve?

Proteins are processed and packaged in the organelle known as the ________.

Calcium ions are normally in higher concentrations outside most living cells than within cells. Which of the following processes is most likely responsible for this condition?

During a 5-mile run in the high Alps, where oxygen concentration is lower, your body will produce less ATP per molecule of glucose than after the same run near sea level, where there is plenty of oxygen to supply your muscle cells. Approximately how many more molecules of ATP will your muscle cells produce per molecule of glucose at the lower elevation than at the oxygen-scarce high elevation?

Which of these is most abundant in the plasma membrane?

Certain organisms break down glucose in the absence of oxygen. This process is called ________.
