Question

which of the following is not a cytoskeleton element? centriole microtubule intermediate filament microfilament question 6 often referred to as the \power plant\ of the cell, which organelle is the site of atp production? endoplasmic reticulum peroxisome lysosome mitochondrion

Explanation:

The cytoskeleton is composed of microtubules, intermediate filaments, and microfilaments. A centriole is an organelle involved in cell - division and not part of the cytoskeleton. The mitochondrion is known as the "power plant" of the cell as it is the main site of ATP production through cellular respiration. The endoplasmic reticulum is involved in protein and lipid synthesis, peroxisomes in breaking down fatty acids and detoxifying hydrogen peroxide, and lysosomes in digesting waste materials and cellular debris.

Answer:

1. centriole
2. mitochondrion
