Following glycolysis and the citric acid cycle, but before the electron transport chain and oxidative phosphorylation, the carbon skeleton of glucose has been broken down to co2 with some net gain of atp. most of the energy from the original glucose molecule at that point in the process, however, is stored in the form of which of the following molecules?
(a) nadh
(b) glucose
(c) pyruvate
(d) acetyl-coa

Energy at this point is stored as NADH

Explanation: Glycolysis is a catabolic reaction that is made of many steps that breaks down food to give off energy in a form of ATP. Pyruvate the product of glycolysis, is converted to Acetyl-coA using enzyme pryruvate dehydrogenase. During this process between krebs cycle and oxidative phosphorylation NAD takens electron (reduction) and turns to NADH(oxidation) which travels to the mitochondria, our power house, where its converted to energy using redox reactions. To sum up, energy from glucose molecules are transported and exist in forms of NAD to NADH.

a unit of heredity that is transferred from a parent to offspring and is held to determine some characteristic of the offspring.

the potatoes have high sugar concentrations and although these potatoes were different we could seethe effects that their sugar concentrations had in different environments. for example, the potatoes in sample a, were placed in pure water. this created a hypertonic environment and caused the potatoes to draw in water from its surroundings. we saw the opposite happen with the potatoes in sample b when placed in the sodium chloride solution. the potatoes in this case were in a hypotonic solution and therefore lost water to their surroundings.
