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.
Answer: Cell membrane has many properties which is stated below.
Explanation:
The cell membrane allow one cell to communicate with other cell. It is the cell membrane which is directly in contact with the cell membrane of the another cell.
The cell membrane also serves as a channel for the transport of materials from the outside to inside and vice versa.
It also provides stability to the cell. It combines with the carbohydrates and provides immune response and cell recognition.
Explanation:
The nucleus (plural, nuclei) houses the cell's genetic material, or DNA, and is also the site of synthesis for ribosomes, the cellular machines that assemble proteins. Inside the nucleus, chromatin (DNA wrapped around proteins, described further below) is stored in a gel-like substance called nucleoplasm.
The nervous system and the muscle system respond to stimuli to produce motion. The skeletal movements of muscles are mostly voluntary.
Involuntary movements occur in these muscles when the nerve impulse passes from a sensory neuron to a motor neuron via an interneuron in the spinal cord.
<h3>What are Skeletal muscles?</h3>
Skeletal muscles may be defined as the muscles that fasten to your bones and authorize you to achieve a broad range of activities and operations.
Skeletal muscles control the direct movement of a person's will and are hence referred to as voluntary movement. While the spinal cord is associated with both movements directly or indirectly. It is a prolonged, delicate tubelike network liable for holding incoming and outgoing messages through the brain to the rest body.
Therefore, it is well described above.
