Question

question 12
which of the following best describes a lysosome?
a contain powerful enzymes capable of digesting worn cellular parts, cho, fats, proteins or substances that ente cell
b a non - membranous structure that is involved in cell reproduction
c a complex network of interconnected membranes that function in communication
d release energy from food molecules and transform energy into usuable form

Explanation:

Lysosomes are membrane - bound organelles. They contain hydrolytic enzymes. These enzymes can break down worn - out cellular components (like old organelles), carbohydrates (CHO), fats, proteins, and substances that enter the cell (such as phagocytosed particles).

• Option B: Lysosomes are membrane - bound. Non - membranous structures involved in cell reproduction are centrioles (in animal cells).
• Option C: A complex network of interconnected membranes for communication is more characteristic of the endoplasmic reticulum (smooth or rough ER).
• Option D: Releasing energy from food molecules and transforming energy into a usable form (ATP) is the function of mitochondria.

Answer:

A. contain powerful enzymes capable of digesting worn cellular parts, CHO, fats, proteins or substances that enter cell
