Answer:

The difference between the microfilaments, intermediate filaments, and microtubules are stated below.

Explanation:

  • Microfilaments:
  1. They are made up of two chains made up of monomeric globular proteins called actin. The chains are coiled around each other.
  2. They have a diameter of about 7 nanometre.
  3. They help in cellular movement.
  • Intermediate Filaments:
  1. They form strands which are made up of fibrous proteins like keratin, vimentin, desmin.
  2. They have a diameter which ranges from 8 nanometre to 10 nanometre.
  3. They have structural function and are required to maintain the cell shape and organelle position.
  • Microtubules:
  1. They are formed when the globular proteins, alpha-tubulin and beta-tubulin form dimer and undergo polymerisation.
  2. They have a diameter of about 25 nanometre.
  3. They form the structural components of flagella, cilia and centrioles. They prevent cell compression.

Naddik [55]

Answer:Cellular respiration is the process of transforming chemical energy into forms usable by the cell or organism. Organisms ingest organic molecules like the carbohydrate glucose to obtain the energy needed for cellular functions. The energy in glucose can be extracted in a series of chemical reactions known as cellular respiration. Most energy is produced during cellular respiration in the mitochondria, a process that involves breakdown of simple sugars to produce energy in the form of ATP, which is the usable form by the cell.
