Myoglobin acts as an oxygen reserve in muscle tissue. It is a protein that binds to oxygen and releases it when needed during periods of low oxygen availability, such as during exercise.
In the case of oxygen dissolved in water, oxygen is the solute and water is the solvent. Oxygen molecules are dispersed (dissolved) in water, which acts as the medium in which the oxygen molecules are distributed uniformly.
A self-inflating mask does not deliver oxygen on its own. It requires a separate oxygen source such as an oxygen tank or concentrator to deliver oxygen to the user. The mask acts as a medium to deliver the oxygen to the person wearing it.
Creatine phosphate acts as an energy storage molecule in muscle cells by donating a phosphate group to ADP to quickly resynthesize ATP during high-intensity exercise. This process helps provide a rapid source of energy for muscle contractions.
Yeast and hydrogen peroxide produce oxygen gas as a byproduct of their reaction. The yeast acts as a catalyst to break down the hydrogen peroxide into water and oxygen.
No, oxygen is not considered a substrate. In biological terms, a substrate is the molecule upon which an enzyme acts to catalyze a chemical reaction. Oxygen is often a reactant in biochemical reactions, such as cellular respiration where it serves as the final electron acceptor.
A musculotropic substance acts on muscle tissue. It specifically targets and affects smooth muscle cells, resulting in changes to muscle contraction and relaxation.

Adipose tissue (fat) acts as a reserve source of energy.
Myoglobin's function is similar to that of hemoglobin, which carries oxygen in red blood cells to various tissues. Myoglobin has even higher affinity for oxygen than hemoglobin and is specific to muscle cells. Myoglobin thus acts as a storage of oxygen, as it holds oxygen inside heart and skeletal muscles.

The Adipose Connective Tissue insulates against heat loss and provides reserve fuel.
Connective tissue, specifically adipose tissue (fat), packages and protects body organs. Adipose tissue acts as a cushioning layer around organs, providing protection from physical impact and supporting their structure within the body.
Adipose tissue, commonly known as body fat, serves as an insulator to help regulate body temperature and as an energy reserve to store excess calories. Insulation helps maintain core body temperature, while stored energy can be used during times of energy deficit, such as fasting or prolonged exercise.
The tissue that acts as a firm protective packing around and between organs, as well as bundles of muscle fibers and nerves, is known as connective tissue. Specifically, adipose tissue and dense connective tissue play crucial roles in providing support, protection, and insulation to various structures in the body. This tissue helps maintain the structural integrity of organs while allowing flexibility and movement.
Fat in the hypodermis provides mechanical cushioning as well as insulation for the body.
Cartilage. This is composed of connective tissue that is not as hard as bone but is stiffer than muscle.
