A physical change is a change which only affects the form of a substance, but not its chemical composition. So, a physical change in terms of particle arrangement states that particles do not change apart from gaining or losing energy. It can be explained using the examples of freezing and melting.
When a substance is solid, its particles like atoms and molecules are very tightly packed. These cannot move freely but when a substance is in liquid or gaseous state, the particles are loosely packed and can move freely. So when water is solid the particles are tight but when it is in liquid state same particles can move faster. Hence, particles are same but their energy has changed.
Answer:
The correct answer is option C) "are processed by proteases into both opiate and non-opioid peptides".
Explanation:
The opioid propeptides, as well as any other propeptides, is a protein precursor that needs to be excised into a smaller form to acquire its active form. The opioid propeptides are processed by proteases into both opiate and non-opioid peptides, where the latter could be active or non active. Opiate peptides are enkephalins, endorphins, and dynorphins that act by blocking secondary systems, such as the ones that cause pain perception.
