Why are red blood cells unable to replace damaged proteins

Biology
1 answer:
Rainbow [258]3 years ago
7 0

The sole reason why red blood cells are unable to replace damaged proteins is that red blood cells lack DNA and cell organelles such as the nucleus, ribosomes, and mitochondria which are crucial for protein synthesis, assembly, and repair. In other words, they lack both the information and the machinery for making or repair of proteins.

Due to lack of DNA and cell organelles, red blood cells cannot be able to satisfy the central dogma which summarizes synthesis of proteins as DNA → RNA → proteins.

DNA has the genetic information on how proteins should be made, RNA is responsible for transferring the information from DNA in the cell nucleus to the ribosomes in the cytoplasm,  then translating or decoding this information, which results in the making of protein.

Scilla [17]

Answer:

Option B, Move closer to your home town

Explanation:

The options for the given question are as follows -

A) Knock down your previous house and build a bigger one.

B) Move closer to your home town.

C) Move further away from your home town.

D) Stay where you are but speed up your daily life

Solution -

Electrons carry negative charge while nucleus carries positive charge due to the presence of positively charged proton ions and neutral ions (which has no charge). All the electrons are attracted towards the nucleus due to its positive charge. The orbit on which an electron revolves around a nucleus has higher energy level as compared to the energy levels located in between the space of electron and nucleus.  

While moving from a high energy orbital to a low energy level orbital, an electron releases some energy.  Hence, in order to move closer to home, electron needs to push itself toward the nucleus by releasing energy

Hence, the given option is B

Which of the following serves as an electron carrier in cellular respiration?
GrogVix [38]

Answer;

-NAD+

Explanation;

-When glucose breaks down into ATP, a large amount of the energy is stored as electron on special molecules (the electron carriers). When an empty electron carrier accepts a pair of electrons, it is reduced; when it gives those electrons up later on, it is oxidized.

-NAD+ and FAD; also the two most common electron carriers in the body. NAD+ can accept a pair of electrons (and a hydrogen ion) to become NADH.

What characteristic of are found in veins but not arteries?
Paul [167]

Answer: Possession of Valves

Explanation: Veins possess valves which ensures that blood flows in only one direction. Valves helps blood to flow back to the heart against gravitational force.

Arteries don't have valves because the pressure originating from the heart is capable of causing the blood to flow in one direction.
