Compare and contrast photophosphorylation and oxidative phosphorylation?
Oxidative phosphorylation is ATP synthesis driven by electron transfer to oxygen and photophosphorylation is ATP synthesis driven by light. Oxidative phosphorylation is the culmination of energy-yielding metabolism in aerobic organisms and photophosphorylation is the means by which photosynthetic organisms capture the energy of sunlight, the ultimate source of energy in the biosphere.
How the metabolic rate of an animal can be determined by measuring its rate of oxygen consumption.?
Oxygen is needed in ATP synthesis by oxidative phosphorylation.
What does NADPH add to the Calvin cycle?
NADH is generated by the electrons transferred to the NAD+. It is used in oxidative phosphorylation of for ATP synthesis later on.
What is the direct energy source that drives ATP synthesis during respiratory oxidative phosphorylation in eukaryotic cells?
the proton-motive force across the inner mitochondrial membrane.
What is the synthesis of ATP from ADP and P?
Phosphorylation
What is the synthesis of ATP from ADP and phosphate?
The process is called phosphorylation.
What is the process of converting energycfrom a light -excited electron into pyrophosphate bond of an ADP molecule?
Most probably it is the substrate-level phosphorylation.
What type of reaction is Mg Cl2- MgCl2?
Salt formation reaction, reducto-oxidative reaction (redox)
What is the enzyme in the mitochondria that helps in the synthesis of ATP?
It's either ATP synthase (if you are studying the end of the ETC part of respiration, where ADP is converted to ATP) through substrate-level phosphorylation or nucleoside-diphosphate kinase (if you are looking at the transfer of a P* from, say, GTP to ADP to make ATP and GDP) through oxidative phosphorylation.
Which enzyme catalyzes glutamate oxidative deamination?
Glutamate dehydrogenase an mitochondrial enzyme helps in oxidative deamination of glutamate It helps to take out the ammonium group from glutamate to make it available for urea synthesis
What is the direct energy source that drives ATP synthesis during respiratory oxidative phosphorylation?
The difference in H+ concentrations on opposite sides of the inner mitochondrial membrane. During oxidative phosphorylation, NADH and FADH oxidizes at the hydrogen carriers to provide electrons to the electron transport chain (etc) (chain of electron carriers) and H+ ions. As electrons pass through the etc, ATP is synthesized. If energy is ever needed along the process, ATP is used. But i doubt it as the electron do not require external chemical energy to move along the carriers.
Where does oxygen come from in oxidative phosphorylation?
when you breathe in, you breathe in oxygen which is then transported to your cells and they use it to and food to respirate.
