Cellular membrane, nucleus, and cytoplasm are the three major components of a cell. Organelles are structures present within a cell and are specialized to perform a particular metabolic task essential for the survival of the cell. Eukaryotic cells consist of several organelles, including Golgi complex, mitochondria, endoplasmic reticulum, flagella and cilia, chloroplast, microfilaments and microtubules, and lysosomes. Similar to a nucleus, mitochondria are also surrounded by a double membrane system. Some microbial eukaryotes get killed by the presence of oxygen (O 2 ). Such microbes do not contain mitochondria and some may possess structures referred to as hydrogenosomes.

Question

Definition Definition Set of metabolic processes and reactions that produce energy from organic substances such as glucose. Cellular respiration takes place in the organism’s cells, where the chemical energy from nutrients or molecules of oxygen is converted into adenosine triphosphate (ATP). Cellular respiration that occurs in the presence of oxygen is called aerobic respiration; in the absence of oxygen, it is called anaerobic respiration.
