In the small intestine, suspended fat droplets diffuse into cells by endocytosis for their nutrient and mineral content. Which b
est describes the process in which these nutrients are absorbed during digestion? A) Protein-lined pits identify needed nutrients and temporarily bind with receptors until fully engulfed into the cell.
B) Large vacuoles are formed by the plasma membrane outside the cell for the transport of large molecules inside the cell.
C) The cell pinches inward, forming a vesicle of solutes suspended in fluids.
D)
Specialized white cells ingest nutrients outside the cell and diffuse across the cell membrane by active transport.
Cellular respiration that proceeds in the absence of oxygen is anaerobic respiration. Cellular respiration that proceeds in the presence of oxygen is aerobic respiration. Anaerobic respiration evolved prior to aerobic respiration.
