Cellular mechanisms involve in many reactions in which the transfer of electrons from one molecule to another by means of redox reactions. Glycolysis is a carbohydrate catabolic pathway in which the oxidation of glucose to pyruvate occurs. It requires two molecules of ATP for initiation of glycolysis and yields four molecules of ATP by oxidation of each glucose molecule. Citric acid cycle is known as the tricarboxylic acid cycle (TCA) in which pyruvate molecules obtained from glycolysis are broken down to release carbon dioxide. The carbon dioxide is formed by the complete oxidation of pyruvate during the aerobic respiration.

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.

Imagine you are a botanist. Below are characteristics of a never-before described plant species recently identified as part of the ‘All Taxa Biodiversity Inventory’ (ATBI). Field Notes: Specimen collected from shaded area along stream in South Cumberland State Park (Grundy County, TN). Laboratory Analysis: Body: Large leaves emerging from underground rhizome. Size: 63 cm Chromosomal Analysis: Plant body is diploid—chromosome number of 44. Lignin test: Positive Cuticle: Present Leaves: Present—large with branched veins. Underside has sori (containing haploid spores). Roots: Present—branch from the inside. Stem: Present—vascular tissue (xylem & phloem) present. Life History: Diploid sporophyte dominant generation. Haploid spores germinate into heart-shaped, haploid, gametophyte. Water required for fertilization; no seed is produced. Diploid zygote develops into sporophyte. Explain which domain, kingdom and phylum you believe this plant should be classified…
