The process of cellular respiration catabolic pathway that breaks molecules into energy
<u>Explanation:</u>
Metabolic pathways consist of two distinct types: catabolic and anabolic. Catabolic deliver energy while breaking down molecules into easier molecules. Cellular respiration is one case of a catabolic pathway. During cellular respiration, sugar is held in by the cell and break to discharge energy that enables us to live.
Cellular respiration is the manner of oxidizing food particles, similar glucose, to carbon dioxide and water. The method transpires in two states:
- glycolysis, the division of glucose to pyruvic acid
- the entire oxidation of pyruvic acid to carbon dioxide and water
Answer:
The correct answer is option A. "The contents of blood come into closer contact with tissues in a closed system than an open system".
Explanation:
In a closed circulatory system, the blood has an specific path, circulating from arteries to veins and to smaller blood vessels throughout the body. This is in contrast with open circulatory systems at which the blood is not contained in arteries or veins but it suffuses the body. A closed circulatory system have many advantages over open circulatory system, however in a closed circulatory system the contents of blood are not into closer contact with tissues in than an open system. Actually, in an open circulatory system the blood is in closer contact with tissues.
