Plants utilize sunlight during photosynthesis to convert carbon dioxide and water into glucose (sugar) and oxygen. This glucose has energy stored in its chemical bonds that can be used by other organisms. This stored energy is released whenever these chemical bonds are broken in metabolic processes such as cellular respiration.
Cellular respiration is the process by which the chemical energy of "food" molecules is released and partially captured in the form of ATP. Cellular respiration is the general term which describes all metabolic reactions involved in the formation of usable energy from the breakdown of nutrients. In living organisms, the "universal" source of energy is adenosine triphosphate (ATP). Carbohydrates, fats, and proteins can all be used as fuels in cellular respiration, but glucose is most commonly used as an example to examine the reactions and pathways involved.
Marathon runners eat a large plate of pasta the night before a competition because pasta is a good source of energy, or fuel for the body. All foods contain energy, but the amount of potential energy stored will vary greatly depending on the type of food. Moreover, not all of the stored energy is available to do work. When we eat food, our bodies convert the stored energy, known as Calories, to chemical energy, thereby allowing us to do work. A calorie is the amount of heat (energy) required to raise the temperature of 1 gram (g) of water 1 degree Celsius (°C). The density of water is 1 gram per milliliter (1g/ml) therefore 1 g of water is equal to 1 ml of water. When we talk about caloric values of food, we refer to them as Calories (notice the capital "C"), which are actually kilocalories. There are 1000 calories in a kilocalorie. So in reality, a food item that is listed as having 38 Calories has 38,000 calories. Calories are a way to measure the energy you get from the food you eat.
Just as pasta can provide a runner energy to run a marathon, a tiny peanut contains stored energy that can be used to heat a container of water. For this lab exercise, you will indirectly measure the amount of Calories in couple of food items using a calorimeter. A calorimeter (calor = Latin for heat) is a device that measures the heat generated by a chemical reaction, change of state, or formation of a solution. There are several types of calorimeters but the main emphasis of all calorimeters is to insulate the reaction to prevent heat loss. We will be using a homemade calorimeter modeled after a constant-volume calorimeter. A particular food item will be ignited, the homemade calorimeter will trap the heat of the burning food, and the water above will absorb the heat, thereby causing the temperature (T) of the water to increase. By measuring the change in temperature (∆T) of a known volume of water, you will be able to calculate the amount of energy in the food tested.
What else can I help you with?
What is form is energy stored in at the end of photosynthesis?
Chemical energy
What energy does cellular respiration convert?
It form chemical energy i.e. ATP (Adenosine Tri-phosphate)
Which organelle converts chemical energy stored in food?
Mitochondria convert chemical energy stored in food molecules into a form of energy that cells can use called adenosine triphosphate (ATP) through a process called cellular respiration. This process takes place in the inner membrane of the mitochondria.
What is considered chemical energy?
Chemical energy is a form of potential energy stored in the bonds of chemical compounds. When a chemical reaction occurs, this energy is released or absorbed. Common examples include the energy stored in food, gasoline, and batteries.
Energy stored in chemicals like food?
Food contains chemical energy stored in the bonds between molecules. When food is digested, these bonds are broken, releasing energy that our bodies can use for various functions like movement, growth, and maintaining body temperature. This energy comes from the sun and is converted into chemical energy through photosynthesis in plants.

Chemical energy
What energy does cellular respiration convert?
It form chemical energy i.e. ATP (Adenosine Tri-phosphate)
What form of energy that stored in batteries and food and many more?
Chemical energy is stored in batteries, food, and other molecules. When these substances undergo chemical reactions, the stored energy is released.
What is food energy stored as?
Chemical energy.
The food we eat has stored?
The food we eat has stored chemical energy from the chemical bonds in the molecules.
Which organelle converts the chemical energy stored in food into compounds that are convenient for the cell to use?
Mitochondria are the organelles responsible for converting the chemical energy stored in food molecules into ATP, which is the primary energy source for cellular activities. This process is known as cellular respiration and takes place in the mitochondria's inner membrane.
What type of energy is stored in batteries and food?
Batteries store chemical energy, which is converted to electrical energy when used. Food stores chemical energy in the form of carbohydrates, fats, and proteins, which our bodies convert into energy through metabolism.
What is food an example of what energy?
Food is an example of chemical energy stored in the form of carbohydrates, proteins, and fats. When we consume food, our bodies convert these molecules into usable energy through processes like digestion and metabolism.
What energy is stored in foods?
The type of energy that is stored in food is called chemical potential energy.. This energy is stored until it is ready to be used.
Is the energy stored in food called electromagnetic energy?
No. The energy in food is chemical energy.
Where the energy and food is stored until it i released?
It is in movement
