Cells in a snake's venom gland release large quantities of protein toxins and use a great deal of energy. These cells contain a nucleus, ribosomes, mitochondria and cytoplasm.
Which pair of statements correctly links two of these structures to the activities of the cells?
ribosomes join amino acids to make the toxins; mitochondria transfer energy from glucose
the nucleus joins amino acids to make the toxins; cytoplasm stores the genetic material
ribosomes transfer energy from glucose; mitochondria control the activities of the cells
mitochondria join amino acids to make the toxins; the nucleus transfers energy from glucose
