Passage Hide
Cells obtain molecules needed to maintain homeostasis by using active transport to move molecules into the
cell or by synthesizing molecules within the cell. Cells also use active transport to remove toxins to maintain
intracellular homeostasis.
At the organism level, homeostasis is maintained in a variety of ways. For example, some organisms move
around their environment to locate food, water, and mates or to avoid danger.
Which statement correctly describes active transport, molecular synthesis, and movement?
Active transport, molecular synthesis, and movement all require energy
Active transport, molecular synthesis, and movement occur in all organisms.
Active transport and molecular synthesis occur in both plants and animals, but movement occurs only in
plants.
Active transport and molecular synthesis don't require energy, but movement does require energy.
