How does an enzyme’s active site relate to its substrate?

1 answer:

5 0

The active site is complementary to its substrate due to its specific 3D structure. The substrate fits in to one specific active site so an enzyme will only bind to one substrate. They are SPECIFIC. Lock and key theory.

Where does nad+ deliver electrons compared to fad in cellular respiration?

Anna71 [15]

Answer:

The correct answer would be "NADH delivers its electrons to complex I and FADH₂ deliver its electrons to complex II" in cellular respiration.

There are mainly four complexes associated with electron transport chain of cellular respiration.

Complex I or NADH: ubiquinone oxidoreductase is the complex at which NADH is oxidized to form NAD⁺. The free electrons are transported with the help of ubiquinone.

Complex II or succinate dehydrogenase is the complex associated with oxidation of FADH₂ to FAD⁺. It also transports the free electrons with the help of the ubiquinone pool.

Complex III or cytochrome bc1 complex transport free electrons from ubiquinone to the cytochrome C which is a water-soluble electron carrier.

Complex IV or cytochrome c oxidase transport the free electrons to oxygen to form water.

AveGali [126]

Answer:

Given that,

$Distance=360\:Kilometres$

$Speed = 720 KM/hr$

$time=360km/720kmh^{-1}$

$time=1/5 hr$

$Time = 30\: minutes \:or \:1/5 \:hours \: or \: 0.5 \:hours.$

Zina [86]

Answer:

The oxygen enters the bloodstream from the alveoli, tiny sacs in the lungs where gas exchange takes place (Figure below). The transfer of oxygen into the blood is through simple diffusion. ... While oxygen moves from the capillaries and into body cells, carbon dioxide moves from the cells into the capillaries.
