BMST - Basic Math and Science Cellular Processes and Organelles Questions and Answers 3

Question 1

Which organelle is responsible for modifying, sorting, and packaging proteins for secretion?

Accepted Answer

Golgi apparatus

Answer

The Golgi apparatus receives proteins from the ER, modifies them, and packages them into vesicles for secretion or delivery to other organelles.

Question 2

What is the term for the process by which a cell engulfs large particles or other cells?

Accepted Answer

Phagocytosis

Answer

Phagocytosis is a form of endocytosis where the cell membrane surrounds and engulfs large solid particles, forming a phagosome.

Question 3

Which structure controls what enters and exits the nucleus?

Accepted Answer

Nuclear pore complex

Answer

Nuclear pore complexes are protein channels in the nuclear envelope that regulate the transport of molecules between the nucleus and cytoplasm.

Question 4

During aerobic respiration, where does the Krebs cycle occur?

Accepted Answer

Mitochondrial matrix

Answer

The Krebs cycle (citric acid cycle) takes place in the mitochondrial matrix, the fluid-filled space inside the inner mitochondrial membrane.

Question 5

What is the function of ribosomes found on the rough endoplasmic reticulum?

Accepted Answer

Protein synthesis

Answer

Ribosomes on the rough ER synthesize proteins that are destined for secretion, insertion into membranes, or delivery to lysosomes.
