Expert Solution

The Proton gradient which is produced by pumping of protons during the Electron Transport Chain (ETC) help to generation of ATP. ATP are produced by ATP synthase enzymes which is present on inner mitochondrial membrane. NADH+H⁺, FADH2 which are produced in TCA cycle and also NADH+H⁺ which are produced in glycolysis are oxidized by different complexes of ETC. There are 4 complexes which remain embedded in the mitochondrial membrane and two mobile electron carrier for the transport of electrons. When NADH+H⁺ ,FADH₂ are oxidized, protons are generated which move from mitochondrial matrix to inner membrane space, located between inner and outer mitochondrial membrane. These H+ ions moves back into mitochondrial matrix by the enzyme F₀F₁ATPase or ATP synthase enzyme. During this process protons move the ATP synthase enzyme and then ADP is converted to ATP. So, without proton movement ,ATP production is not possible in animal cells.

Plant cells are different from animal cells in several ways. All plant cells have a cell wall during their entire existence. The cell wall has many different functions in different cell types. Compare and contrast between the two types of plant cell walls as to their chemical make up, shape, when they are formed, and morphological properties. Include all chemical components in the cell wall we discussed during lecture. Draw two figures showing how each of these cell walls are...

Glucose is a necessary substrate for ATP production in many cells, particularly the neurons in the nervous system. Inability to maintain blood glucose between meals leads to feelings of fatigue. There are many steps in the extraction of energy from glucose for production of usable energy in a cell. Please discuss the extraction of energy from glucose by cells for both aerobic and anaerobic energy processes. Calculate the energy yield per molecule of glucose for each process (show your work)....

Comparing plant cells and animal cells Plant cells and animal cells share many of the same structures, but each type of cell also has unique structures.

Part A - Comparing plant cells and animal cells Plant cells and animal cells share many of the same structures, but each type of cell also has unique structures. In this activity, you will indicate which cell structures are found only in plant cells, only in animal cells, or in both plant and animal cells. Drag each cell structure to the appropriate bin. If a structure is found in both plant cells and animal cells, drag it to the "both"...

All cells contain ion pumps that use the energy at ATP hydrolysis to pump ions across the plasma membrane. These pumps create an electrochemical gradient across plasma membrane, including some transport processes In animal cells, the main ion pump is the sodium potassium pump.
