Answer: a.myoglobin
Explanation:
Myoglobin (Mb) and Hemoglobin (Hb) are heme proteins and are part of the family of globular proteins. These proteins are characterized by having the spherical or globular wrapped polypeptide chain having various types of secondary structures. Myoglobin is an extremely compact protein found in muscular cells of vertebrate animals, having as their main function the storage and it also facilitates the transport of oxygen in the muscles. This protein is found in the cardiac muscle and skeletal muscle of the mammals and increases the effective solubility of oxygen in the muscle by acting as an oxygen reservoir and facilitating the diffusion of O2 from the capillaries blood to the mitochondria.
Answer:
It is the most abundant
Explanation:
The four most abundant elements by mass in the human body are other nonmetals including oxygen (65%), carbon (18%), hydrogen (10%), and nitrogen (3%). The most abundant of the other nonmetals in the Earth's crust is oxygen which is the single most abundant element in the Earth's crust.
Cellular Respiration is the process of producing ATP by breaking down carbon based molecules when oxygen is present. The reactants are glucose and oxygen. It then produces carbon dioxide, water and energy (ATP). This process is important because it provides energy that your body needs and could not live without!
If I am understanding the choices correctly, the answer would be Convection Currents.
Hope this helps!
