Portage Learning Question and answers correctly solved 2024 List two organs contained in the abdominal cavity. - correct answer The abdominal cavity contains the stomach, intestines, spleen and liver True or False? a. Cellular respiration occurs in the mitochondria. (T or F) b. The purpose of cellular respiration is to produce ATP. (T or F) c. Integral proteins are only found on the inner surface of a cell membrane. (T or F) d. Endocytosis is the process that occurs to eject biomacromolecules from the cell. (T or F) e. Pinocytosis uses a signaling molecule from another cell, binding to the cell membrane to bring about changes within the cell proteins. (T or F) - correct answer a. True b. True c. False d. False e. False You are observing two cells under the microscope. They are the same type of eukaryotic cell but one appears much larger. Based on appearance alone, which one would you expect to be carrying out respiration at a more active rate, the larger or smaller cell? Explain why. - correct answer I believe it is the smaller cell that will breathe at a more active rate because in order for respiration to occur efficiently and more actively the surface area to volume ratio is very critical; also, if the larger surface area is present then the diffusion of gases occur at a higher rate; so, larger cells will have a smaller surface to volume ratio and diffusion that will occur at a slower rate creating a less active respiration; and, on the other hand smaller cells will have a larger surface area to volume ratio and an improved diffusion rate, so the higher rate and more active respiration. The smaller cell. Cells need to remain relatively small because as a cell expands the amount of surface area relative to the volume of the cell decreases. The smaller cell is more active because relative to its volume, its surface area is larger than a bigger cell. With a larger surfa
