Question

question 10 0.5 pts which of the following is not a component of the endomembrane system? lysosome golgi apparatus endoplasmic reticulum mitochondrion nucleus question 11 0.5 pts the process by which a cell engulfs a foreign particle is known as: endofusion phagocytosis membrane synthesis hydrolysis endosymbiosis question 12 0.5 pts which of the following is most likely to have the greatest concentration of rough endoplasmic reticulum? a cell that secretes enzymes a cell that engages in photosynthesis a cell that destroys pathogens a cell that makes steroid hormones a prokaryotic cell

Explanation:

• Question 10: The endomembrane system includes the nuclear envelope, endoplasmic reticulum, Golgi apparatus, lysosomes, and vesicles. Mitochondria are not part of it as they have their own unique functions and origin.
• Question 11: Phagocytosis is the process by which a cell engulfs a foreign particle. It is a form of endocytosis used by immune - cells like macrophages to remove pathogens.
• Question 12: Rough endoplasmic reticulum is associated with protein synthesis. Cells that secrete enzymes (which are proteins) require a large amount of rough endoplasmic reticulum for protein production.

Answer:

• Question 10: D. mitochondrion
• Question 11: B. phagocytosis
• Question 12: A. a cell that secretes enzymes
