Penicillin is Choose one: A. produced by a mold and was discovered accidentally. B. a human-designed antibiotic, synthesized to

NeX [460]

Answer:

Option-A

Explanation:

Penicillin is an antibiotic drug that is derived from the fungal species of Penicillium molds especially the Penicillium notatum. The penicillin acts by disrupting the formation of the cell wall and thus prevents the growth of the bacteria.

The discovery of penicillin was accidental when he was studying the petridish of staphylococcus and he found that due to avoidance while the experiment, molds grew in the petridish. The area around the mold was clear and clear rings without the bacteria were easily observed. This lead to the discovery of the penicillin compound.

Thus, Option-A is the correct answer.

Question 4

Juliette [100K]

Answer:

In eukaryotes, thousands of chemical reactions are able to take place in separate compartments called organelles.

Explanation:

Organelles are specific cellular structures that are the means of compartmentalizing the various functions that occur within cells.

Examples of organelles and their functions are:

- Nucleus: contains DNA and in it occur the replication of this molecule and its transcription into RNA.

- Rough endoplasmic reticulum: protein synthesis and conjugation of these molecules occurs.

- Mitochondrion: houses all oxidative phosphorylation reactions and the electron transport chain for ATP synthesis to occur.

The organelles are then the structures that allow the development of the multiple functions that a cell has.

The other options are not correct because:

Bacteria is a prokaryotic organism.
Prokaryote refers to simple organisms that lack organelles.
Proteins are biomolecules that allow the structure and function of living beings.
