When NADH is the electron donor to the respiratory chain, 2.5 ATP are formed, but when FADH2 is the electron donor, only 1.5 ATP
Fofino [41]

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.

The cholesterol associated with animal cell membranes
bekas [8.4K]

Cholesterol is one of the molecules composing the cell membrane. b) makes the cell membrane fluid at room temperature.  

<h3>What is the role of cholesterol in the cell membrane?</h3>

The cell membrane is composed of two lipidic bilayers, cholesterol, proteins, and glucans incrusted in between.

Cholesterol is one type of lipid.

These molecules are incrusted in the membrane between the hydrophobic tails of lipids.

Their proportion on both sides of the membrane is almost the same.

Cholesterol is a significant molecule that contributes to the membrane fluidity, separates phospholipids, and interact with membrane proteins regulating in their activity.

The correct option is b). makes the cell membrane fluid at room temperature.

what term describe Movement of gases across the respiratory membrane in the pulmonary capillaries or into the alveoli?
Pavlova-9 [17]

Answer:

<em>At the respiratory membrane, where the alveolar and capillary walls meet, gases move across the membranes, with oxygen entering the bloodstream and carbon dioxide exiting. It is through this mechanism that blood is oxygenated and carbon dioxide, the waste product of cellular respiration, is removed from the body.</em>
