See that big ball of light in the sky?
When sunlight hits your skin, Vitamin D is produced.
I dont know if you are considering vitamins a food molecule or not, but liquids also contain energy. As do cardboard, glue, and everything else you mice and rats eat.
Cockroaches can live for years off of the paper and cellulose glue used on you wallboard. (drywall)
What else can I help you with?
Why the grams of the nutrient molecules in a food do not add up to the total gram weight of the food?
The total weight of a food item includes not only the weight of the nutrient molecules but also water, fiber, and other non-nutrient components. Nutrient molecules like carbohydrates, proteins, and fats only make up a portion of the total weight because they are typically smaller molecules that are densely packed with energy. This is why the grams of nutrient molecules in a food may not add up to the total weight of the food item.
Molecules which serve as chemicals to make reaction work- like the breakdown of food molecules?
They are called enzymes. They aren't necessarily considered molecules, but I suppose they are, perhaps very large ones. These enzymes act as a catalyst to speed the decompositions along. Stomach acid helps by oxidising the food as well as creating the environment for the proteins to function.
Can electrical energy be transformed into chemical energy?
Yes, electrical energy can be used to facilitate chemical reactions that create chemical energy stored in molecules like batteries. This conversion is often seen in processes like electrolysis or in the charging of batteries.
A gaseous system at equilibrium with its surroundings as molecules of A collide with molecules of B without reacting the total energy of the gaseous system decreases increases or remain same?
The total energy of the gaseous system remains the same. In an ideal gas, the kinetic energy of the molecules is the only form of energy that affects the system's total energy. Collisions between A and B molecules will redistribute this kinetic energy, but the total energy of the system (sum of potential and kinetic energy) will not change.
Why food coloring dissolves faster in hot water than cold water?
Food colouring dissolves faster in hot water because the water molecules have more energy and they move around more creating larger gaps for the food colouring molecules to fit into, while the cold water has less energy and the water molecules are closser together making it harder for the food colouring to dissolve
What is food energy needed for?
Food is necessary for survival because the food contains glucose, and glucose is the only source of energy for living organisms.
When you digest food is it a new substance?
No, digestion only breaks food down into simpler molecules, such as starches into sugars. The total amount of the basic elements remains unchanged with most of it being passed through as an ineffective source of energy.
The main difference between chemo synthetic autotrophs and photosynthetic autotrophs is that only?
Chemolithoautotrophs use inorganic compounds as an energy source in chemosynthesis, while photoautotrophs use sunlight as an energy source in photosynthesis. This difference in energy source influences the way these organisms produce organic molecules for growth and development.
What is the only energy source that the brain can use?
Glucose is the only energy source that the brain can use.
Role of energy in the body?
Food provides our energy source - energy is needed to extract the oxygen from the atmosphere and diffuse it into our bloodstream. As warm blooded animals we can only digest food and function if our bodies are at 37C - energy is required for this. We need energy to move our muscles which also only operate when they are warm
Is a carbohydrates polymer function?
Carbohydrates or polysaccharides are the primary source of energy for our body.Our brain only uses glucose as its energy source.Carbohydrates are easy to breakdown and if that is not available in diet body tries to get energy from fat molecules.
Give 4 reasons why you need food?
I can only think of 1 reason why you need food:-Food is broken down into molecules which cells use to create a chemical reaction which provides energy to your body. Without energy, you would die.
Why the grams of the nutrient molecules in a food do not add up to the total gram weight of the food?
The total weight of a food item includes not only the weight of the nutrient molecules but also water, fiber, and other non-nutrient components. Nutrient molecules like carbohydrates, proteins, and fats only make up a portion of the total weight because they are typically smaller molecules that are densely packed with energy. This is why the grams of nutrient molecules in a food may not add up to the total weight of the food item.
Why is it important that living organisms use food as a source of energy?
because food is the only way to intake energy.Sleeping just rests your body it won't give you energy. Unless you know photosynthisis.....that would be cool
Does a plant only require the correct chemicals to make plant food?
No. A plant also uses sunlight, an external source of energy.
What is meant by the amount of energy that can be derived from food?
When you eat your body will split the molecules of the food into smaller molecules. When this reaction releases energy. This energy is used to form ATP molecules. ATP molecules are used in the human body to preform actions and because of this it generally refers to energy. Different types of food will result in different amounts of ATP molecules. Because it's made of different substances, one will always be more efficient then the other. This way differs the amount of energy that can be derived from food. I hope this answers your question. Please correct me if I made a mistake. But please be gentle when correcting my spelling and grammar, English ain't my native language :).
Is a bulb a source of energy?
No, a bulb is not a source of energy. A bulb simply converts electrical energy into light energy. The electrical energy is usually provided by a power source, such as a battery or a power outlet.
