The right option is; C) anaerobic respiration; lactate
Anaerobic respiration is a cellular respiration that occurs in absence of oxygen. In this process, glucose is broken down into molecules without oxygen to produce energy which is transferred to the cell with the production of lactic acid. Anaerobic respiration is used by eukaryotic cells such as in human muscles during extraneous activities when the oxygen supply is low. There is high production of lactic acid (lactate) which provides the required energy (ATP molecules) for cellular activities. This weaken the muscles and it can cause painful muscle cramps.

The purpose of the transport proteins is to protect the cell's internal environment and to keep its balance of salts, nutrients, and proteins within a range that keeps the cell and the organism alive. There are four main ways that molecules can pass through a phospholipid membrane.
