How chemical composition of proteins diffee from that of fats​
aivan3 [116]

Proteins are different from fats and carbohydrates due to the presence of nitrogen, carbon, hydrogen, and oxygen in them. Carbohydrates only contain carbon, hydrogen, and oxygen whereas fats contain fatty acids which contain a carboxyl group and an alkyl group, thus containing only carbon, oxygen, and hydrogen.

How many ATP are generated in the electron transport chain?<br> оооо<br> 2<br> 4<br> 32<br> 36
Svetllana [295]

Answer:

32 ATP <em>molecules are generated in the </em><em>electron transport chain.</em>

<em><u>Explanation:</u></em>

The cell used a process known as Chemiosmosis and to produce ATP. The energy released from the <em>electrons during the electron transport system and they pump the protons.</em> The energy is transferred into higher energy bond of ATP and they are made to perform their cell work.

<em>'Electrons are the subatomic particles that orbit the nucleus of an atom'. They are always negative in charge and are always smaller than the 'nucleus of the atom'.</em> The electron transporters are arranged in series and they are embedded into their inner mitochondrial membrane and they are shuttles the electrons from '\mathrm{NADH}^{\prime} and '\mathrm{FADH}_{2}' to the molecular oxygen. In this process, the protons are pumped through the 'mitochondrial matrix' to 'the intermembrane space' and the oxygen level is lowered to form the water.

How does replication of the lagging strand of DNA compare with replication of the leading strand?
Natali5045456 [20]

Answer: The correct answer is- B) Okazaki fragments are made on the lagging strand but not on the leading strand.

DNA replication is a biological process in which two identical replica of DNA are produced from single original DNA molecule through an enzyme called DNA polymerase.

The strands of double helical DNA are first separated ( with the help of helicase enzyme) so that the template DNA strands are exposed. DNA is synthesised in 5' to 3' direction.

Leading strand ( whose template strand is 3' to 5') is synthesized in continuous manner as DNA polymerase moves along the direction of replication folk.

Whereas lagging strand ( whose template strand is 5' to 3') is synthesized in a discontinuous manner as it requires multiple primers to synthesise the DNA. It generates small fragments of DNA called okazaki fragments.
