Digestion?
Breaking down of food occurs in multiple places
1) salivary amylases break down simple sugars
2) pepsin in the stomach breaks down some proteins
3) digestion is completed in the duodenum of the small instestine by pancreatic amylases, lipases, and peptidases (trypsin and chymotripsin) which break down sugar, fats, and proteins respectively.
bile produced by the liver also aids in the digestion of lipids, serving as an emulsifier.
Energy is released by the digestion of food, but is absorbed in the other parts of the small intestine (jujenum and ileum) by finger like productions called villi. Villi absorb amino acids (remnants of proteins), vitamins, and monosaccharides. The lacteal within the villi absorbs fatty acids and glycerol (remnants of lipids)
A living organism uses the process of cellular respiration to release stored chemical energy from nutrients. This process involves breaking down glucose molecules to produce ATP, which is the energy currency of the cell.
The cellular process of breaking down food to release energy is called cellular respiration. During cellular respiration, glucose is broken down in the presence of oxygen to produce ATP, the cell's main energy source. The process occurs in the mitochondria of cells and involves several biochemical steps to extract energy from the food molecules.
Exothermic processes release energy. These processes involve a decrease in the overall energy of the system, leading to the release of thermal or light energy to the surroundings. Examples include combustion reactions and some types of chemical reactions.
Photolysis is a chemical reaction that breaks down a compound into smaller components using light energy. The process involves the absorption of photons by the compound, which then leads to the cleavage of chemical bonds and the formation of new products.
Excite electrons and enter a higher energy state, triggering the process of photosynthesis. This results in the conversion of light energy into chemical energy that can be used by the plant.
When a mineral breaks down and releases energy, it is known as a chemical reaction or a chemical process. This process may involve the release of heat, light, or other forms of energy as bonds are broken and new substances are formed.
metabolism
The process is respiration (cellular respiration). It breaks down the compounds called carbohydrates to release the energy stored there (which almost always originally came from photosynthesis).
When fossil fuels are burned, they undergo a chemical reaction with oxygen in the air to release heat energy. This process breaks the chemical bonds within the fossil fuels, resulting in the release of stored potential energy in the form of heat.
The chemical process that breaks down nutrients is called digestion. In this process, enzymes break down nutrients such as carbohydrates, proteins, and fats into smaller molecules that can be absorbed by the body for energy and other functions.
Yes, energy from food is considered chemical energy. When we consume food, our body breaks down the chemical bonds in the food molecules to release energy that our cells can use for various biological processes.
Glycolysis is a metabolic pathway that breaks down glucose into pyruvate and generates ATP and NADH in the process.
When a fuel is burned, it is a combustion reaction. This reaction breaks apart chemical bonds and releases the energy stored in them.

A living organism uses the process of cellular respiration to release stored chemical energy from nutrients. This process involves breaking down glucose molecules to produce ATP, which is the energy currency of the cell.
A chemical reaction in your body in which bonds are broken is associated with catabolism, the process of breaking down larger molecules into smaller ones to release energy. This process is essential for generating energy for cellular activities and overall metabolism.
Chewing food breaks it down into smaller pieces, increasing its surface area for enzymes to act on, which helps in releasing the chemical energy stored in the food. This process also aids in the efficient absorption of nutrients by the body.
