Answer: The Quaternary structure
Explanation: Myoglobin and hemoglobin are both hemeprotiens with the ability to bind oxygen.
Myoglobin is mainly found in muscle tissue and plays a vital role as an intracellular storage site for oxygen. Myoglobin is a monomeric heme protein and has a secondary and tertiary structure. Hemoglobin is vital for the transportation of oxygen from the lungs to the rest of the body as needed. Hemoglobin is a tetrameric hemeprotien with secondary and tertiary structures.
Both hemoglobin and myoglobin are absent of a quaternary structure.
Answer:
The total energy production of a mitochondrion is enhanced by its large internal surface area.
Explanation:
All cellular activity requires energy, it is through mitochondria that this energy necessary for cell activity will be generated. Mitochondria has a large internal surface area, all of which strongly influences the energy production of this organelle.
To get energy, the cell necessarily needs glucose. Mitochondria have the function of breaking down glucose by introducing oxygen into carbon, what remains is carbon dioxide, which will come out through exhalation. This process performed by this important cellular organelle is known as cellular respiration. In order for cells to perform their functions normally, they depend on various chemical reactions that occur within the mitochondria.
Despite its great importance, mitochondria is a fairly small cell organelle. There are cells that have a large number of mitochondria, however, the amount of this organelle will depend on the function of each one. The more the cell needs energy to perform its vital functions, the more mitochondria it will produce.
