ANATOMY

Detailed explanation-1: -Anaerobic respiration is a normal part of cellular respiration. Glycolysis, which is the first step in all types of cellular respiration is anaerobic and does not require oxygen. If oxygen is present, the pathway will continue on to the Krebs cycle and oxidative phosphorylation.

Detailed explanation-2: -There are two types of cellular respiration: aerobic and anaerobic. One occurs in the presence of oxygen (aerobic), and one occurs in the absence of oxygen (anaerobic). Both begin with glycolysis-the splitting of glucose. Glycolysis is an anaerobic process-it does not need oxygen to proceed.

Detailed explanation-3: -Anaerobic respiration is the process by which cells break down sugars to produce energy without oxygen. Anaerobic respiration is also called fermentation. Fermentation mainly occurs in yeast cells, bacteria, and muscle cells of animals.

Detailed explanation-4: -Anaerobic stands for “without oxygen.” This method of cellular respiration does not require oxygen to generate energy. For smaller animals to breathe, there is not enough oxygen available so they need the energy to survive in the absence of oxygen.
