1. Which of the following is NOT evidence for the endosymbiotic origin of mitochondria?
They have a double membrane
They have internal ribosomes
They produce ATP
2. Which type of structure is required for muscle cell contraction?
Intermediate filaments
Actin microfilaments
Chloroplasts
3. The name of the protein used by cells to create cytoskeletal filaments needed to organize organelles is which of the following?
Tubulin
Intermediate filaments
Actin
They have a double membrane
They have internal ribosomes
They produce ATP
Explanation / Answer
Question No 1
Answer: They produce ATP
Question No 2.
Answer: Actin microfilaments
Question No 3.
Answer: Tubulin
(Intermediate filaments provide mechanical strength and resistance to shear stress.Microtubules determine the positions of membrane-enclosed organelles and direct intracellular transport. Actin filamentsdetermine the shape of the cell's surface and are necessary for whole-cell locomotion.)
