Answer:
im pretty sure its the 3rd one
Explanation:
Answer:
The characteristics of allosteric enzymes are listed below.
Explanation:
1 They may have binding sites for regulatory molecules that are separate from the active site.
2 They tend to have sigmoidal curve of V0 vs [S].
3 They undergo conformational change as a result of modulator binding
Answer:NADH donates it electron to complex I a higher energy level than other complexes while FADH donates it electron to complex II a lower energy complex.
Explanation:
Both NADH and FADH are shuttle of high energy electrons originally extracted from food into the inner mitochondrial membrane.
NADH donate it electron to a flavoprotein consisting of FMN prosthetic group and an iron-sulphur protein in ETC complex-I. Two electrons and one hydrogen ion are are transferred from NADH to the flavin prosthetic group of the enzyme.
While the electrons from FADH2 enters the ETC (electron transport chain) at the level of co-enzyme Q (complex II). This step does not librate enough energy to act as a proton pump.
So NADH produces 2.5 ATP during the ETC and oxidative phosphorylation because it donates its electron to Complex I, which pump more electrons across the membrane than other complexes.
Titan's rivers, lakes, and seas of liquid methane and ethane could provide a habitable environment on the moon's surface, though any life there would most likely be very different from life on Earth.
Methane gas is effective at trapping heat and burns quickly. As a result, methane is one of the most important human fuels. Furthermore, methane in the atmosphere helps to regulate the Earth's climate.
Over the first 20 years after it enters the atmosphere, methane has more than 80 times the warming power of carbon dioxide. Even though CO2 has a longer lasting effect, methane drives warming in the short term. Methane from human activity is responsible for at least 25% of today's global warming.
As a result, methane not only contributes to global warming directly, but also indirectly through the release of carbon dioxide.
