Question

Quizplus · Accepted Answer

The cytoskeleton is an internal framework composed of a network of protein structures, such as microfilaments, intermediate filaments, and microtubules.

Answer: G
 Cylindrical structures made of tubulin proteins are microtubules, which are part of the cytoskeleton.

Answer: A
 Cellular extensions that move substances along the cell surface are typically cilia or flagella, which are composed of microtubules and are part of the cytoskeleton.

Answer: D
 Structures that increase surface area of the plasma membrane for absorption are generally microvilli, which are also composed of microfilaments and are part of the cytoskeleton.

Answer: H
 The genetic control center of the cell is the nucleus, which is not part of the cytoskeleton.

Answer: I
 ATP synthesis occurs in the mitochondria, which are not part of the cytoskeleton.

Answer: J
 Intracellular digestion occurs in lysosomes, which are not part of the cytoskeleton.

Answer: B
 Protein synthesis occurs in the ribosomes, which are not part of the cytoskeleton.

Answer: C
 Substances that are packaged for release from the cell are typically stored in vesicles, such as secretory vesicles or lysosomes, which are not part of the cytoskeleton.

Answer: E
 Cholesterol and fat synthesis occurs in the smooth endoplasmic reticulum, which is not part of the cytoskeleton.
