List-I		List-II
(a)	Amphetamines	(i)	Clears ammonia from blood
(b)	Aspartic acid	(ii)	Initiates buffering system
(c)	Alkaline	(iii)	Initiates fat metabolism
(d)	Caffeine	(iv)	Neuromuscular excitation

Select the correct option :

Amphetamines are a type of synthetic stimulant drug that increase the release and inhibit the reuptake of certain neurotransmitters in the brain, such as dopamine, norepinephrine, and serotonin.

These neurotransmitters play a role in regulating mood, attention, and behavior.

Amphetamines are often used to treat medical conditions such as attention deficit hyperactivity disorder (ADHD) and narcolepsy, but they can also be abused recreationally for their stimulant effects.

Aspartic acid is an amino acid that plays a role in the urea cycle, which is the process by which ammonia, a toxic byproduct of protein metabolism, is cleared from the blood.

Aspartic acid combines with ammonia to form argininosuccinate, which is then converted into arginine, another amino acid that is involved in the urea cycle.

The urea cycle takes place in the liver and helps to convert ammonia into urea, which is then excreted from the body in the urine.

Therefore, aspartic acid is involved in the detoxification of ammonia from the blood.

Caffeine is a stimulant that can increase the metabolic rate of the body, leading to an increased breakdown of fat (lipolysis).

Caffeine acts on the nervous system and stimulates the release of certain hormones, such as adrenaline, which can activate the enzyme lipase that breaks down stored fat into free fatty acids that can be used for energy.
