Answer:
The statement true of all proteins, carbohydrates and fats is that human body is able to synthesize them all.
The statement unique to proteins is that proteins are made up of instructions according to DNA.
Explanation:
Carbohydrates, Proteins and fats are macronutrients and required by body in larger amounts. All these macromolecules are made up of building blocks like proteins are from amino acids, carbohydrates from monosaccharides and fats from triglycerides. Human body can also synthesize these macronutrients. Like proteins can be synthesized by central dogma. Glucose can be synthesized by gluconeogenesis from glycogen and fats can be synthesized from acetyl-CoA and NADPH.
The proteins are made up by a process known as central dogma. The first step of central dogma is replication in which a replicated copy of DNA is produced in a cell. The second step is transcription for the production of messenger RNA from DNA. At last mRNA is used for the production of proteins on ribosomes.
Aerobic cellular respiration takes place in the presence of oxygen and anaerobic cellular respiration takes place in the absence of oxygen.
Similarities:
- As a beginning molecule, glucose is used in both aerobic and anaerobic respiration, which is a similarity. The substrate is what you see here.
- Additionally, both aerobic and anaerobic respiration results in the production of ATP, but aerobic respiration generates far more ATP than anaerobic respiration.
- In both situations, food is oxidized and energy is liberated.
Differences:
- Anaerobic respiration occurs when there is no oxygen present, whereas aerobic respiration occurs when there is oxygen.
- Alcohol is produced by anaerobic respiration, whereas carbon dioxide and water are the byproducts of aerobic respiration.
- Compared to anaerobic respiration, aerobic respiration produces more energy.

Answer:
The neurons are unable to repolarize.
Explanation:
The cell membrane potential remain negative at the resting membrane potential. The potassium channels maintains the negative voltage inside the cell and makes the cell stable at resting membrane potential.
The scorpion agitoxin affects the potassium channels, the depolarize cell remains in the depolarize state because potassium channels are inhibited. The cells are unable to repolarize as the potassium channels are unable to enter in the cells.
