Question

1. which of the following structures of a eukaryotic cell is not likely derived from an endosymbiotic bacterium? (0.5pts) options: lysosome, golgi apparatus, rough endoplasmic reticulum, smooth endoplasmic reticulum, mitochondrial dna, mitochondrial ribosomes, inner membrane, outer membrane

Explanation:

1. For question 14: The Golgi apparatus is responsible for modifying proteins, including adding sugar groups (glycosylation) to them. The smooth ER handles lipid synthesis, rough ER handles protein synthesis, and lysosomes handle digestion.
2. For question 15: The endosymbiotic theory states mitochondria evolved from engulfed bacteria; they have their own DNA, ribosomes, and inner membrane (from the original bacterium). The outer membrane comes from the host cell's membrane, so it is not derived from the endosymbiotic bacterium.

Answer:

1. Golgi apparatus
2. Outer membrane
