When examining an endocrine cell from a new species of mammal under the microscope you find that it contains an abundance of rou
gh endoplasmic reticulum, a large Golgi apparatus, and secretory granules. Which of the following is most likely to be true about these cells? 1. It secretes a peptide/protein hormone. 2. It secretes its product by diffusion through the lipid bilayer of the plasma membrane.3. It secretes by endocytosis.4. Its hormone product is synthesized from cholesterol. 5.It secretes a hormone with a hydrophobic structure.
The above mentioned answer is more likely true for this question.
Because, rough endoplasmic reticulum is the cytoplasmic organelles which are involved in post-translational modification of peptide chains. After that, peptide chains are further modified (folded) in golgi apparatus. It's means that abundance of rough endoplasmic reticulum and golgi apparatus present in cells ensure the formation and secretion of peptide/protein hormones.
One hypothesis that is in the scientific community which relates to the origin of the building blocks for life is that they were formed when lightning struck water.
