Question

topic: cell functions and organelles
\another example of a genetic organelle disease is pompe. this is a progressive disease that affects the function of the lysosomes. this disease causes muscle weakness and respiratory failure due to a buildup of glycogen in tissues.\
which statement best describes the structure and function of the cell organelle where glycogen builds up in individuals with pompe disease?
a. the organelle has a flexible membrane that helps it store water.
b. the organelle has an acidic ph that activates enzymes that break down cellular waste.
c. the organelle has a flexible membrane that breaks off into vesicles to transport materials around the cell.
d. the organelle has inner folds that provide more surface area for the chemical reactions that break down cellular waste.
reasoning:

topic: cell functions
nyles used a microscope to observe two different types of cells.
drawings of the two cells are shown below.
which of the following best contrasts the functions of the cell parts labeled x and y?
a. part x stores water for future use, whereas part y releases water out of the cell.
b. part x holds the structures in place in the cell, whereas part y keeps all molecules from leaving the cell.
c. part x provides energy for the cell, whereas part y helps with photosynthesis in the presence of sunlight.
d. part x regulates substances that enter or exit the cell, whereas part y provides protection and support to the cell.
reasoning:

Explanation:

1. For the first question about Pompe disease: Lysosomes are the organelles affected in Pompe disease. They have an acidic pH which activates enzymes to break - down cellular waste. Option B describes lysosome characteristics correctly.
2. For the second question about cell parts X and Y: Typically, the cell membrane (could be X) regulates substances entering and exiting the cell, and the cell wall (could be Y) provides protection and support to the cell. Option D best contrasts their functions.

Answer:

1. B. The organelle has an acidic pH that activates enzymes that break down cellular waste.
2. D. Part X regulates substances that enter or exit the cell, whereas part Y provides protection and support to the cell.
