Bacterial Energetics and Membranes Abstract The Mg2+/Ca2+ ATP synthase present in all bacterial membranes‚ particularly E. coli‚ couples ATP synthesis to the proton (H+) gradient produced by the ETC‚ a process known as oxidative phosphorylation. The gradient acts to power the ATPase‚ so that it may phosphorylate ADP to produce ATP. The reverse reaction of this process‚ or hydrolysis of ATP into ADP and Pi‚ may be used to observe ATPase activity when the resulting Pi is quantitatively measured

When the mitochondrial membrane became "leaky" to hydrogen ions chemiosmosis stopped because there wasn ’t a gradient of protons between the outside and inside of the membrane. Without a gradient of protons the majority of the ATP produced by cellular respiration couldn ’t be produced which is essential to make fatty acids and breakdown glucose‚ therefore the energy in a persons metabolism comes from stored fat or protein‚ causing a person to lose weight as well as causing a lack of energy. In the same

This suggests a positive correlation. Plants require sunlight‚ water and carbon dioxide to grow. These are necessary in the process of photosynthesis‚ which makes glucose for the plants. The glucose is then used by the plant in the process of cellular respiration in order to make energy. 8. Conclusion:

2. Describe the steps involved transforming energy from burning glucose to synthesis of ATP. Cellular respiration‚ in the process of ATP synthesis‚ refers collectively to intercellular reactions in which energy-rich molecules are broken down to form ATP‚ using O2 and producing CO2 (2). In most cells‚ ATP is generated from the disassembling of absorbed nutrient molecules in three stages‚ glycolysis: in the cytosol‚ the citric acid cycle: in the mitochondrial matrix and oxidative phosphorylation: at
