Answer:
They probably use aerobic respiration.
Explanation:
A travel distance of 11.500 kilometers in 9 days covered by flying surely requires a lot of energy.
- If cells are fermenting, the ATP (energy) they generate only comes from glycolysis, which produces 2 ATP molecules.
- If they are using aerobic respiration, glucose is completely oxidized to CO₂ through glycolysis and the Citric Acid Cycle, and the electrons enter the electron transport chain to finally reduce oxygen into water. In the complete process, up to 36 ATP molecules are produced.
In sum, aerobic respiration is much more efficient to generate energy than fermentation, so it's probably the main metabolism of the flight muscles in bar-tailed godwits.
Answer:
In most tissues of the body, the response to hypoxia is vasodilation. By widening the blood vessels, the tissue allows greater perfusion. By contrast, in the lungs, the response to hypoxia is vasoconstriction.
Explanation:
Answer:
Reflected ray
Explanation:
The angle between a reflected ray and the normal drawn at the point of incidence to a reflecting surface is the angle of reflection.
Answer: The main function of mitochondria is to produce energy for the cell. Cells use a special molecule for energy called ATP.
Explanation: The most prominent roles of mitochondria are to produce the energy currency of the cell, ATP (i.e., phosphorylation of ADP), through respiration, and to regulate cellular metabolism. The central set of reactions involved in ATP production are collectively known as the citric acid cycle, or the Krebs cycle.
