Answer

To determine which substance plays an important role in mood changes among the options provided (Aspirin, Noradrenaline, Lansoprazole, and Zantac), we can analyze each option step by step:

### Step 1: Analyze Aspirin
Aspirin is primarily known as an analgesic (pain reliever) and anti-inflammatory medication. It is commonly used to treat pain, fever, and inflammation. However, it does not have a direct effect on mood or emotional states.

**Hint:** Consider the primary function of each medication and whether it relates to mood or emotional well-being.

### Step 2: Analyze Noradrenaline
Noradrenaline (also known as norepinephrine) is a neurotransmitter and hormone that plays a significant role in the central nervous system. It is involved in the body's response to stress and can influence mood. Increased levels of noradrenaline are associated with feelings of euphoria and improved mood, making it a key player in mood regulation.

**Hint:** Think about how neurotransmitters affect mood and emotional states.

### Step 3: Analyze Lansoprazole
Lansoprazole is a proton pump inhibitor used to reduce stomach acid and treat conditions like gastroesophageal reflux disease (GERD). Its primary function is related to digestive health, and it does not have any known effects on mood or emotional well-being.

**Hint:** Focus on the therapeutic uses of the medication and whether they relate to mood changes.

### Step 4: Analyze Zantac
Zantac (ranitidine) is also used to reduce stomach acid and treat conditions like ulcers and heartburn. Similar to Lansoprazole, it does not have any direct effects on mood or emotional states.

**Hint:** Consider whether the medication addresses psychological or emotional health.

### Conclusion
After analyzing all four options, it is clear that **Noradrenaline** plays an important role in mood changes due to its effects on the central nervous system and its association with feelings of euphoria and well-being.

**Final Answer:** Noradrenaline is the substance that plays an important role in mood changes.
