d. white blood cell that engulfs bacteria

Accepted Answer

Hello everyone. So today we're going to be talking about the mitochondria. Well the mitochondria is the most important organ L of eukaryotic cells because they are involved in the manufacture and supply of energy to the cells. So the number of mitochondria in a sale depends on let's go over answer choices. Keeping in mind that these mitochondria is going to be involved in the production of energy or respiration. Let's begin actually by answer choices B. And E. The reason why we're putting this together is that they both relate to photosynthesis. Remember that the mitochondria is involved in respiration. It is not going to be directly involved in photosynthesis. This is the function of the colon oppressed because of this. We're going to be canceling our answer choices B. And D. Because photosynthetic activity of the cell and the availability of life both related to photosynthesis which is not the function of the mitochondria. Moving on we have answer choice A. The size of the cell. Well the size of the cell is not directly related to the energy expenditure of the cell. Some very small cells require tons of energy because they have a lot of activity. While other very large cells do not require as much energy because they're mostly immobile and do not require as much energy or as much mitochondria to be present because of this. We're also going to cancel this out. And this all leaves us with the physiological activity of this cell. Let's call this physiological activity just exercise. So sales that are undergoing out of exercise. Such as muscle cells. These are cells that need to be contracting and moving a lot are going to require a lot of mitochondria because they're going to be using a lot of energy. So these cells that have very high physiological activity, who are exposed to a lot of exercise and a lot of movement are going to be the cells that have the most mitochondria and produce the most energy. Because of this, the correct answer choice is going to be answer choice. Physiological activity of the cell is the primary determinant on the number of mitochondria that the cell has. I really hope this video helped you and I hope to see you on the next one.
