Fully explain how cellular respiration is a chemical process whereby the bonds of food molecules and oxygen molecules are broken
Marianna [84]
Cellular respiration is a metabolic pathway that breaks down glucose and produces ATP. The stages of cellular respiration include glycolysis, pyruvate oxidation, the citric acid or Krebs cycle, and oxidative phosphorylation.

During cellular respiration, a glucose molecule is gradually broken down into carbon dioxide and water. Along the way, some ATP is produced directly in the reactions that transform glucose. Much more ATP, however, is produced later in a process called oxidative phosphorylation. Oxidative phosphorylation is powered by the movement of electrons through the electron transport chain, a series of proteins embedded in the inner membrane of the mitochondrion.
These electrons come originally from glucose and are shuttled to the electron transport chain when they gain electrons.


As electrons move down the chain, energy is released and used to pump protons out of the matrix, forming a gradient. Protons flow back into the matrix through an enzyme called ATP synthase, making ATP. At the end of the electron transport chain, oxygen accepts electrons and takes up protons to form water. Glycolysis can take place without oxygen in a process called fermentation. The other three stages of cellular respiration—pyruvate oxidation, the citric acid cycle, and oxidative phosphorylation—require oxygen in order to occur. Only oxidative phosphorylation uses oxygen directly, but the other two stages can't run without oxidative phosphorylation.).

Human papillomavirus (HPV) is a double-stranded DNA virus that enters the cytoplasm before undergoing uncoating. Although the vi
Roman55 [17]

Answer:

Basal cells, keratinocyte

Explanation:

The viral DNA replication is inhibited until<u> Basal cells</u>  are differentiated into <u>keratinocyte</u>, which are ready to be shed from the epithelial layer, increasing the likelihood that HPV will be transmitted to a new host.

95% of the cells in the epidermis are keratinocytes

Basal cells are multipotent stem cells that are important in the regeneration of homeostasis of the respiratory epithelial cell population.

in skin growth, most of the cells are keratinocytes and they are formed by the division of stem cells in the basal layer
