What is cellular respiration? use complete sentences to explain how the mass of carbon is conserved during cellular respiration.

heres what i have so far. i don't really know how to answer the other part:

cellular respiration is a set of processes that convert biochemical energy from glucose into chemical energy.

cellular respiration is actually a oxidation reaction, where the food in the presence of oxygen gets oxidized and energy is released, this energy is stored in the form of ATP .

Cellular respiration is  a set of processes that convert biochemical energy from glucose into an energy molecule that is stored for later use. In this process, when you consume food one molecule of glucose is turned into about 38 molecules of ATP. Well, even though the chemical energy in glucose is being converted to the cellular energy in ATP, the nutrition remains the same. Energy is neither created nor destroyed. Cellular respiration begins in a cell's cytoplasm, where the glucose molecule is initially broken down. The rest of the process mostly happens in the mitochondria, a-k-a the power house of a cell.This is important because during cellular respiration, lots of chemical reactions are happening in the inner membrane to convert glucose into ATP. So your cells already used the glucose from the food you consume and made some ATP, but the rest of the food is basically useless to your body. And as an efficient machine, your body will eliminate it in a concise and timely manner.

Hope This Helps!

answer : one can design an experiment using a liquid and an additive that can be added to the liquid and observe the chemical changes in the reaction species.

one would need a beaker which is filled with a known amount of the liquid in which thermometer is placed to measure the temperature changes; after addition of the additive to the liquid solution one can note down the temperature change and find whether the reaction is endothermic or exothermic in nature. by subtracting the initial temperature value with the final temperature one can find the temperature changes.

various combinations of liquid and additive can be used. liquid in this case can be a known quantity of water and additives can be epsom salt or without epsom salt the experiment can be conducted to notice the changes. water and ice, hydrogen peroxide and dry yeast, vinegar and baking soda,etc.
