Answer:
Correct answer is c. It is the final electron acceptor in the aerobic respiration.
Explanation:
Oxygen is a substrate of the aerobic respiration, but it is not the only one. Glucose is also a substrate.
Oxygen is used in the cells to be the final electron acceptor, this means that receives the electrons from NADH and FADH2. That is why, when there is no oxygen available for aerobic respiration, the NADH and FADH2 cannot be oxidized and therefore remain in their reduced form. As a consequence, they cannot be re-utilized during different cellular processes that are NAD+ and FAD dependant, such as glycolysis, pyruvate oxidation and cellular respiration. This means that the ATP synthesis stops.
Oxygen itself does not transport any electrones, this are transported by the cytochrome complex in the mitochondrial membrane. But oxygen is key in receiving those electrones, therefore a very important piece of the electron transport across the mitochondria.
Answer: The potential sources of vitamin B-12 are:
--> Hard boiled egg and
--> Yogurt
Explanation:
Vegetarians are individuals that involves in a dietary practice whereby they avoid some foods such as meat and by products of meat. This is practised by these individuals either due to the health benefits or for some religious beliefs.
There are different types of vegetarians, these include:
--> strict vegetarians
--> lacto vegetarians
--> Ovo vegetarians
--> Pesco vegetarians
--> partial vegetarians and
--> lacto Ovo vegetarians.
LACTO OVO VEGETARIANS are those vegetarians that exclude meat, poultry, and fish but take plant-based foods, dairy products, and eggs. They can obtain vitamin B-12 from hard boiled eggs and yogurts. This is so because, Vitamin B12 is naturally found only in animal foods such as meat, fish, seafood, poultry, eggs, milk, yogurt and cheese. Since the lacto ovo vegetarians do not feed on meat, fish or seafood, the potential sources of vitamin B-12 for a person who follows a lactoovovegetarian dietary pattern are hard boiled egg and dairy products such as yogurt
