Sugar molecules can be oxidized in the cell of animals . This oxidation releases energy for the animal to use. From what soured do the cells get these molecules.

through digested food

Explanation: cells get their sugar molecules from the food that is taken in by an organism. The food taken in is digested by the stomach into base materials like sugar, fatty acids and amino acids. These base materials are circulated through the blood till they get to the cells where they are needed.

The sugar is derived from the breaking down of the carbohydrate molecules in the food we eat during digestion

Explanation:

The cells get the molecules from the food we eat. The food we ingest which consists mostly of carbohydrates, fats and oils and proteins are too complex and must be broken down into smaller molecules before they can be consumed by the body cells.

The process of the breakdown of food starts from the chewing and mixing of the food with saliva after which breakdown by enzymes takes place in the intestine and in the lysosomes.

The carbohydrates are broken down into sugar, the proteins into amino acids and the fats and oils into fatty acids and glycerol.

most voltage drop calculators want the distance between the source and destination. then internally, they double it so both the source and return wires are calculated. but you need to know which distance the calculator uses so you're not half of what you should be or double what you should be.

most circuit breakers will not take a #6 directly, so the electrician will have to splice on a smaller pigtail. you also have to upsize the grounding wire when you upsized the ungrounded (hot) wire (see note in 250.122). this will preclude using most cable assemblies, as a cable with #6 copper will most likely only have a #10 grounding conductor. you need a #6 grounding conductor if the circuit is 20a. a #8 cable is no better, as it will have a #10 grounding conductor too. but most 20a breakers will take a #8 directly.

in your related post, you didn't say what type of load this is. if it is a light or heater, voltage drop won't be a big issue. if this is a motor, the current needs are huge at startup and the voltage drop can pose a problem. if this is a motor, knowing if the motor is under much load during startup will answer the voltage drop effect (a saw is easier to start than a compressor).
