Answer:
300 kcal of energy.
Explanation:
Grass produces 30,000 kcal of energy through the process of photosynthesis. The zebra eat this grass and would acquire 3000 kcal of energy because only 10% of energy will transferred from one trophic level to another. In this way, when the cheetah feed on zebra, it acquire 300 kcal of energy and again 10% of energy is transferred from zebra to cheetah while the remaining release in the atmosphere in the form of heat energy.
Answer:
The correct statement about the hemoglobin and myoglobin is as follows:
1. Each hemoglobin molecule can bind four oxygen molecules; each myoglobin can bind only one oxygen molecule.
3. By itself, heme is not a good oxygen carrier. It must be part of a larger protein to prevent oxidation of the iron.
4. Both hemoglobin and myoglobin contain a prosthetic group called heme, which contains a central iron atom.
5. Heme is composed of an organic protoporphyrin component and a metal atom.
6. Each iron atom can form six coordination bonds: One of these bonds is formed between iron and oxygen.
