Which of the following molecular motors is associated with intermediate filaments?
azamat

Answer: d. none of the other answers

Explanation:

Enzymes that turn chemical energy into mechanical work are molecular motors.

There are three main components of cytoskeleton including microtubules, actin filaments and Intermediate filaments. Only actin  filaments and microtubules carry the motor-driven transport on the cytoskeleton.

The most important feature of intermediate filaments is to provide the plasma membrane with mechanical support where it comes into contact with the extracellular matrix and other cells.

Unlike microtubules and microfilament , intermediate filaments are not involved in motility of the cells, hence do not associat with molecular motors.

Hence, the correct option is d.

The electron transport chain is named for Select one: a. the removal of unnecessary electrons from the cell b. the conversion of
Colt1911 [192]

Answer:

The correct answer is e. the passage of electrons from one energy-generating carrier to another

Explanation:

The electron transport chain is a series of proteins and organic molecules found in the inner membrane of the mitochondria. Electrons pass from one member of the transport chain to the next in a series of redox reactions. The energy released in these reactions is captured as a proton gradient, which in turn is used to form ATP in a process called chemosmosis.

These transport molecules, in the inner mitochondrial membrane, are reduced and oxidized, accepting electrons and transferring them to the next molecule, electrons descending from high energy levels to lower ones, that is, from one energy-generating carrier to another. When lowering to other levels, energy is released that will be used in the synthesis of ATP by oxidative phosphorylation.
