C) inclusion bodies.
D) peroxisomes.

Question

Quizplus · Accepted Answer

Carboxysomes are structures found in obligate chemolithotrophs that contain high levels of enzymes involved in the Calvin cycle, such as RuBisCO. They are thought to play a role in concentrating CO2 for use in carbon fixation. Lysosomes are membrane-bound organelles involved in intracellular digestion, inclusion bodies are aggregates of proteins or other macromolecules, and peroxisomes are involved in lipid metabolism and oxidative stress responses.
