We get the energy to do things from a chemical reaction in our body that requires food molecules and oxygen. Food molecules and oxygen are generated by plants in a process called photosynthesis. We eat food and breathe in oxygen. The larger food molecules become subunits (such as glucose) in a chemical reaction called breakdown. Finally, our bodies use oxygen and glucose in the cellular respiration process to generate energy for our cells.
Photosynthesis is the process in which plants get energy from the sun to transform water and carbon dioxide into oxygen and glucose sugars. Almost all the oxygen we breathe comes from green plants. The sugars created are then stored and used as food for the plant. The food then is used to give the plant …show more content…
(Many of these food molecules are created by plants through photosynthesis.) The proteins, starches, carbohydrates, and other foods that we eat are digested and broken down inside our digestive systems before cells can use them for energy or building material. First, our body breaks down the food into subunits (proteins into amino acids, carbohydrates into glucose, etc.). The cells can use these subunits for energy, and the rest is stored as fat in the body for when the body may need energy later. In the text it states: Evidence. This helps support my claim because it shows how breakdown is a process that makes the food molecules small enough to get inside the cells and ready for the body to convert them into …show more content…
Cellular respiration is a chemical reaction that provides cells with energy from food molecules. The cells break down sugars into forms that cells can use for energy. Similar to photosynthesis, during cellular respiration, a glucose molecule is eventually broken down into carbon dioxide and water, specifically:
1 glucose molecule + 6 oxygen molecules → 6 carbon dioxide molecules + 6 water molecules + energy
The body exhales the carbon dioxide away. In cellular respiration, organisms convert the chemical energy of the food molecules to thermal energy and other types of energy that provide fuel for our cells. Evidence. This shows how energy occurs during cellular respiration. The energy transfer in cell respiration start with a cell releasing chemical energy to fuel cellular actions.------------------------------------------------------ This is supported by out text:-----------------------------.
