Cellular respiration
Aerobic metabolism requires the use of oxygen. In this process, glucose is broken down in the presence of oxygen to produce ATP, the cell's energy currency. Aerobic metabolism is more efficient than anaerobic metabolism, which occurs in the absence of oxygen.
A facultative anaerobe can switch between using oxygen and not using oxygen for metabolism, while a facultative aerobe can only use oxygen for metabolism.
Cells use a process called cellular respiration to convert oxygen and food molecules into energy. This involves breaking down glucose into energy in the presence of oxygen, releasing carbon dioxide and water as byproducts. The energy produced is stored in the form of ATP (adenosine triphosphate) for the cell to use.
Cells can use aerobic (oxidative) and anaerobic (glycolytic) pathways. The availability of oxygen determines which pathway is being used; aerobic pathways are utilized in the presence of oxygen, while anaerobic pathways are used when oxygen is limited. Oxygen is essential for the electron transport chain in aerobic metabolism, while glycolysis can proceed in the absence of oxygen.

Cyanide
Cyanide.
Carbon monoxide is a gas that can block aerobic metabolism by binding to hemoglobin in red blood cells more strongly than oxygen, preventing adequate oxygen delivery to tissues. This interference can disrupt the cell's ability to use oxygen for energy production through aerobic metabolism.
Yes.
A facultative anaerobe can switch between using oxygen and not using oxygen for metabolism, while a facultative aerobe can only use oxygen for metabolism.
Anaerobic organisms do not use oxygen in their metabolism. These organisms can generate energy through fermentation or anaerobic respiration, which does not require oxygen. Examples include certain types of bacteria and yeast.
metabolism
Anaerobes lack the necessary enzymes to neutralize the harmful byproducts of oxygen metabolism, such as reactive oxygen species. These byproducts can damage the anaerobe's cell components, ultimately leading to cell death. In contrast, aerobes have evolved mechanisms to efficiently manage and use oxygen for energy production.
Cyanide is a chemical that blocks aerobic metabolism by binding irreversibly to cytochrome c oxidase, an essential enzyme in the electron transport chain of mitochondria. This prevents cells from utilizing oxygen, leading to cellular asphyxiation and ultimately cell death.
Yes, cyanide blocks aerobic metabolism by binding to cytochrome oxidase in the mitochondria, preventing the cells from using oxygen for energy production. This results in the inhibition of the electron transport chain and the production of ATP, leading to cell death.
