Answer:
the answer is: A) growth of actin filaments to form bulges in the plasma membrane.
Explanation:
Amoebas are unicellular organism that can move on a surface using pseudopodia (false feet). This kind of movement is called amoeboid movement. The amoeboid movement is explained by the Sol-gel theory.  The protoplasm of the amoeba is made of an outer gelatinous layer, and an inner portion made up of plasma sol. The sol-gel theory explains the contraction and relaxation events in the protoplasm of the amoeba that lead to the pseudopodia.

You know that during cellular respiration, energy is converted from glucose, in the presence of oxygen, into numerous ATP molecules. Glucose contains lots of energy, but that energy must be converted into a form usable by cells.
