Answer: The electron transport chain consists of complexes which are the proton pump for the hydrogen ions across the mitochondrial membrane which allows the synthesis of the ATP (energy currency).
Explanation:
The electron transport chain occurs in the mitochondria. ATP synthase present in the inner mitochondrial membrane is a carrier of electron. FADH2 AND NADH two molecules supply high energy electrons from the citric acid cycle from the electron transport chain at complex I (NADH coenzyme Q reductase) and II (succinate dehydrogenase)respectively.
YES.
The thirst mechanism always underestimates fluid loss during work, in the heat and after work ends. Therefore you should take frequent drinks through out the work period. If you drink 250mililitres every 15 minutes, you can replace one litre per hour. if sweat rate is higher you will find it extremely difficult to keep up with fluid needs. During prolonged periods of work in the heat, weight loss exceeds 2 percent therefore the person should rehydrate before returning to work.
The facial nerve (cn vii) passes through the opening in the temporal bone called the stylomastoid foramen.
<h3>Stylomastoid foramen:</h3>
The foramen between the styloid and mastoid processes of the temporal bone of the skull is known as the stylomastoid foramen. It serves as the facial canal's terminus and carries the facial nerve and stylomastoid artery. Bell's palsy may be brought on by facial nerve irritation in the stylomastoid foramen. An unexplained episode of facial muscular paralysis or weakening is known as Bell's palsy. Over the course of 48 hours, it gets worse suddenly.
The stylomastoid foramen is where the 7th cranial nerve leaves the skull and enters the parotid gland at its deep surface. The nerve splits into two major branches, the temporofacial branch, and the cervicofacial branch, right next to the parotid duct.
