B

Keep in mind that total energy in the beginning and after work remains the same according o thermodynamics theory that energy can't be created or destroyed.

Explanation:

Conversion of energy from one form to another is not 100% efficient. Even the transfer of energy from one object to another (work) is not 100% efficient. This also applies to cells. The inefficiencies are lost as heat energy. Examples of such work in the cells include active transport by cell membrane protein channels, metabolic pathways, and etcetera. Some energy in the hydrolysis of ATP to power these biochemical activities is lost as heat which is part of the reason we remain warm. This energy ends up being lost into the environment as heat (e.g even from sweating).

Answer:

If you are referring to the image below, the answers would be:

Monosaccharides:

  • Galactose
  • Glucose
  • Ribose
  • Deoxyribose
  • Glyceraldehyde
  • Fructose

Disaccharides:

  • Maltose
  • Sucrose
  • Lactose

Storage Polysaccharides:

  • Starch
  • Glycogen

Structural Polysaccharides:

  • Chitin
  • Cellulose
  • Amylopectin
  • Amylose

Explanation:

Monosaccharides are simple sugars, typically having 3 to 7 carbons in its structures. Aldoses and ketoses are forms of monosaccharides. If a monosaccharide has a aldehyde, it is an aldose. If a monosaccharide has a ketone, it is a ketose. You also have other forms, depending on te number of carbons. (e.g. Tioses, hexose and pentose)

Disaccharides are two monosaccharides bonded covalently through a glcosidc bond. They form through a condensation reaction, specifically through dehydration synthesis. Thus, the name "di" saccharides.

Polysaccharides are complex carbohydrates that are made up of many monosaccharides. Their functions are mainly storage and make up the structure of tissues.

Storage polysaccharides are polysaccharides that act as food reserves or energy reserves. They are called storage because they are stored away for later use. Starch is a storage polysaccharide that is found in plants and glycogen on the other hand, is found in animals.

Structural polysaccharides help form the structures of cell walls in plants and skeletons in animals. The most common ones are chitin and cellulose.

The aerobic system of energy production uses glycogen, but primarily ______ as its energy source?
Dmitry_Shevchenko [17]


The aerobic system of energy production uses glycogen, but primarily glucose  as its energy source.

Glucose is taken in by the cell and broken into pyruvate in the process of glycolysis, the first step in aerobic cell respiration. It takes place in the cell cytoplasm.

Pyruvate is then used in the Krebs cycle in the cell mitochondria in the second step of respiration which produces high energy electron carriers. These high energy electron carries such as NADP are then employed in the electron transport chain, the last step of the respiration process, where a large number of ATP molecules is produced.

By the time the process of aerobic respiration ends, 36 to 38 molecules of ATP are produced from one single molecule of glucose.

Rudiy27
The larynx is mostly made of cartilage, 3 paired (arytenoid, corniculate, cuneiform) and 3 unpaired (epiglottic, thyroid, and cricoid). The larynx is attached to the hyoid bone in humans and positioned lower in the throat. This decreases the nasality of the sound and increases the tonality as well as the resonance of the sound produced by the larynx which is required for effective communication.
