Myoglobin
O produces the end plate potential.
is a protein involved in the direct phosphorylation of ADP.
o holds a reserve supply of oxygen in muscle cells.
O breaks down glycogen.

holds a reserve supply of oxygen in muscle cells.

Explanation:

Myoglobin is an iron-containing protein whic is found in the muscle cells. It is similar to hemoglobin with respect to its structure. The main function of myoglobin is to store oxygen in the muscle cells that is need for muscles functioning. Myoglobin receives oxygen from the red blood cells and transports it to the mitochondria of muscle cells, where the oxygen is used in cellular respiration to produce energy. The organism can utilize the oxygen in its lungs for a much longer period of time if the concentration of myoglobin becomes high in the muscle cells,

Myoglobin, a molecule similar to hemoglobin, holds a reserve supply of oxygen in muscle cells (third option).

Explanation:

Myoglobin is a protein found predominantly in skeletal or heart muscle fiber, with a chemical structure that, like hemoglobin, contains a heme prostetic group with iron atoms, capable of fixing oxygen.

For this reason, it is a molecule that allows the muscle to have an oxygen reserve, necessary to meet the demand during movement and physical exercise.

Myoglobin has a red color, depending on its heme group. Each iron element of the heme is found in the middle of the protoporphyrin ring, and its ferrous oxidation state Fe²⁺ or ferric Fe⁺³ is the characteristic that allows it to fix or yield oxygen.

answer:

convection currents in the magma drive plate tectonics. heat generated from the radioactive decay of elements deep in the interior of the earth creates magma (molten rock) in the aesthenosphere. the aesthenosphere (70 ~ 250 km) is part of the mantle, the middle sphere of the earth that extends to 2900 km.

picture a world where computers are building made-to-order personalized robotic arms and synthetic organs, drones are circulating above mars! due to the rapid growth of technology, the future has never been more unpredictable, and it presents a huge challenge in education: we are teaching students how to work in a future that we have never been unsure of. it is widely predicted that in eight years’ time, there will be more jobs in the fields of science, mathematics, technology and engineering than in any other discipline. and, as the technology continues to develop, it will soon become clear that addressing social problems will involve more innovative thinking, and analytical and technical knowledge than ever before. undeniably, there are no subjects that encourage innovative and creative thinking, deep thought, problem solving and independence more than the stem subjects. while it is widely commented on that there is a need to reimagine the ways stem subjects are taught in schools by embracing a more interactive and innovative approach to appeal to more students, it should come as no surprise that some of the most reputable educational organizations in the world are already implementing changes to embrace stem. harvard, for example, announced in 2014 that they were increasing their computer science faculty by over 50% and has since introduced computer science as a core subject for all freshmen. the urgency of supporting stem subjects at a young age is becoming more relevant than ever, as adopting a keen interest in the curricula needs to happen early. however, beyond the age issue is one of gender.
