PATHOLOGY

Detailed explanation-1: -An aerobic organism or aerobe is an organism that can survive and grow in an oxygenated environment. In contrast, an anaerobic organism (anaerobe) is any organism that does not require oxygen for growth. Some anaerobes react negatively or even die if oxygen is present.

Detailed explanation-2: -Aerobic organisms use molecular oxygen (dioxygen; O2) to generate chemical energy in the form of adenine triphosphate (ATP). Energy transforms cellular structure to function, a defining property of life.

Detailed explanation-3: -Aerobic bacteria require oxygen for survival. They are present in aerated moist soil containing organic carbon sources.

Detailed explanation-4: -An obligate aerobe is an organism that requires oxygen to grow. Through cellular respiration, these organisms use oxygen to metabolise substances, like sugars or fats, to obtain energy. In this type of respiration, oxygen serves as the terminal electron acceptor for the electron transport chain.
