Step by step
Solved in 2 steps with 2 images
- Describe in general terms the structural makeup of a mitochondrion.In the presence of oxygen, the mitochondrion in yeast is used for aerobic respiration,however, under anaerobic conditions,the yeast mitochondria have been found to have other function. Identify and briefly discuss four of these functionsexplain why oxidative phosphorylation is an emergent property of the mitochondria
- How does DCPIP act as an indicator of presence of mitochondria? Will mitochondria in the presence of DCPIP still make ATP? Why or why not?It has been estimated that mitochondria occupy 20% of the volume in the human body. For a 70- kg adult, the average number of mitochondria has been estimated to be 1 × 10 (10,000 trillion). Using this information, provide a rough estimate of the average mass of a mitochondrion.a) Explain how in oxygenated tissue your cells use your MITOCHONDRIA to produce energy: DESCRIBE the processes occurring in your MITOCHONDRIA (intermediate stage, Krebs, and ETC), Make sure to mention where those processes occur.b) How many ATP per glucose are formed in your mitochondria? Where are they formed?
- How many ATP molecules are made when 40 protons flow from the intermembrane space to the matrix in healthy human mitochondria?The rate of oxygen consumption by mitochondria increases markedly when ADP is added and then returns to its initial value when the added ADP has been converted into ATP (Figure 18.39). Why does the rate decrease?Why is IMPDH in the mitochondria?
- What is the function of cristae in the mitochondrion?Sketch the double-membrane system of the mitochondrion and show where electron transfer chains and ATP synthases are located.Describe the main functions of the different components of the ATP synthase enzyme in the mitochondrion. A structurally similar enzyme is responsible for the acidification of lysosomes and endosomes. Given what you know about the mechanism of ATP synthesis, explain how this acidification might occur.
