Answer:
The correct answer is option c "Proteins that are excreted by prokaryotes are synthesized on ribosomes that are bound to the cytoplasmic surface of the plasma membrane".
Explanation:
Many prokaryotes secrete proteins, particularly, extracellular enzymes that have a function outside the cells and toxins that are not needed by the cell. As any other protein, proteins that are excreted by prokaryotes are synthesized on ribosomes that are bound to the cytoplasmic surface of the plasma membrane. However, excreted proteins go to the general secretion (Sec) pathway, where they are tagged and further processed.
Answer:
B. Microbes may produce unique proteins useful in genetic research
Explanation:
Biodiversity refers to the diversity of living beings present on Earth. The biodiversity is a very important component of the ecosystem as these living organisms are interlinked with each other. Therefore, the loss of biodiversity will affect the ecosystem.
When we look at the biodiversity a layman considers the living organisms which can be seen with eyes but the diversity also exists at the level of the micro-organisms.
The man-made activities are not only harming the macroscopic but also microscopic organisms. The microbes play an important role in our life like these days they are used by the scientific community to study the genetic and related fields like molecular biology. The microbes produce proteins that are consumed by humans.
Thus, Option-B is correct.
