Correct answer: Glycogen
Glycogen is a form of polysaccharide of glucose molecule which serve as energy storage unit in the humans. The excess glucose in the body is stored in the form of glycogen in the muscles and the liver.
The muscles can store upto 500 gram of glycogen and liver can store 100 gram of glucose. Therefore, any carbohydrate which is consumed beyond this limit are converted to and stored as fat.
Glycogen that are stored in muscle are broken down into glucose while the liver cell glycogen are broken down into glucose as a circulating energy source to be used by the body.
Answer: D. a genetic bottleneck
Explanation:
A genetic bottleneck also known as a population bottleneck is one that describes a sharp reduction in the size of a population caused by environmental events like in the above or caused by human activities.
Answer:
Water (H2O)
Explanation:
Light reactions of photosynthesis release oxygen as a by-product. In the presence of sunlight, photolysis of water molecules occurs. Splitting of two water molecules obtains four electrons, four protons, and molecular oxygen. The oxygen-evolving complex, also called the water-splitting complex is associated with photosystem II (PS II). Splitting of water occurs in the oxygen evolving complex and the released electrons are passed one at a time to the reaction center of PS II. Therefore, a water molecule serves as a source of oxygen released during photosynthesis.
