(1) reproductive hormones
(2) carbohydrates
(3) antibodies
(4) biological catalysts
Answer and Explanation:
All of the answer choices are molecules in our body. Let's look at the definition of each choice one at a time. Reproductive hormones such as testosterone and estrogen function to regulate reproductive functions such as menstrual cycle, sperm production etc.
Carbohydrates are molecules from which our bodies derive energy in the form of ATP.
Antibodies protect our bodies from the invasion of foreign particles (pathogens)
Biological catalysts, or enzymes help our body speed up and perform all of the reactions that need to be done such as cutting and copying DNA. Therefore, choice (4) is the correct answer choice.
Answer:
Explanation:
The surface of smooth endoplasmic reticulum that faces the cytoplasm lacks ribbon hence the name smooth endoplasmic reticulum.
The surface of the rough endoplasmic reticulum facing the cytoplasm is studded with ribosomes hence the name rough endoplasmic reticulum.
Both are part of the endomembrane system
The smooth ER functions in the detoxification of drugs.
The rough ER due to the fact that it is students with ribosomes also functions in protein synthesis
The smooth ER coupled with the detoxification of drugs or excess alcohol also help in the synthesis of lipids.
