Answer: B. To provide structural support and strength to tissues such as skin, bones, and cartilage
Explanation: Collagen is a type of protein that is found in various parts of your body. Its structure as a protein allows it to provide rigid structure and support to skin, bones, and cartilage, as well as providing elasticity to skin. As we age, collagen production naturally decreases, which results in our skin naturally becoming more wrinkly as we get older.
Choice A is a function carried out by red blood cells and the hemoglobin protein they carry, not collagen.
Choice C is a function carried out by the thyroid gland and pancreas. These two endocrine organs are responsible for releasing hormones that regulate metabolism and energy production.
Choice D is a function carried out by various neurotransmitters and the myelin sheath. Once an electrical signal reaches the end of a neuron, neurotransmitters are released to continue the signal down to subsequent neurons while the myelin sheath speeds up electrical conduction.
