Which cellular structure stores hormones and other substances and packages these substances into secretory granules?
A) Golgi apparatus
B) Endoplasmic reticulum
C) Mitochondria
D) Lysosome
A
Feedback:
The golgi apparatus stores hormones and other substances. The endoplasmic reticulum contains ribosomes, which synthesize proteins, including enzymes that synthesize glycogen, triglycerides, and steroids and those that metabolize drugs and other chemicals. The mitochondria generate energy for cellular activities and require oxygen. Lysosomes are membrane-enclosed vesicles that contain enzymes capable of digesting nutrients (proteins, carbohydrates, fats), damaged cellular structures, foreign substances (bacteria), and the cell itself.
