Understanding Glyoxysomes

What is the primary structural similarity between glyoxysomes and peroxisomes?

• Both contain chlorophyll.

• Both are enclosed by a single membrane.

• Both are enclosed by a double membrane.

• Both are involved in photosynthesis.

In which plant tissue are glyoxysomes most commonly found during seed germination?

• Cotyledons

• Roots

• Leaves

• Stems

Which organisms, besides plants, contain glyoxysomes?

• Bacteria

• Certain yeasts and filamentous fungi

• Viruses

• Animals

What is the main function of the glyoxylate cycle in glyoxysomes?

• To convert carbohydrates into proteins

• To synthesize lipids from proteins

• To convert acetyl-CoA from fatty acids into carbohydrates

• To break down sugars into fatty acids

Besides the glyoxylate cycle, what other process are glyoxysomes involved in?

• Protein synthesis

• Fatty acid beta-oxidation

• DNA replication

• Photosynthesis
