4 Photosythesis And Cellular Respiration Quiz

Glucose is commonly referred to as sugar because it is a type of sugar that is found in many foods and is the main source of energy for the body. It is a simple carbohydrate that is easily broken down and used by cells for energy production. Therefore, sugar is an appropriate term to describe glucose.

Photosynthesis is an endothermic chemical reaction because it requires energy from an external source, usually sunlight, to convert carbon dioxide and water into glucose and oxygen. The process absorbs heat and light energy, which is used to drive the reaction and produce glucose, a form of stored energy. This is why plants are able to convert sunlight into food through photosynthesis.

During cellular respiration, energy is stored in the form of ATP. ATP, or adenosine triphosphate, is a molecule that carries energy within cells. It is produced during the process of cellular respiration, where glucose is broken down and converted into ATP through a series of chemical reactions. ATP serves as the main energy currency of the cell, providing the necessary energy for various cellular processes and activities.

During photosynthesis, oxygen is released into the environment. This is because photosynthesis is the process by which plants, algae, and some bacteria convert sunlight, carbon dioxide, and water into glucose and oxygen. Oxygen is produced as a byproduct of this process and is released into the atmosphere, where it is used by other organisms for respiration.

During cellular respiration, carbon dioxide and water are released into the environment. This process occurs in the mitochondria of cells and involves the breakdown of glucose to produce energy in the form of ATP. As glucose is broken down, carbon dioxide is produced as a waste product, which is then released into the surrounding environment. Additionally, water is also a byproduct of cellular respiration, as it is formed when oxygen combines with hydrogen atoms during the electron transport chain. Therefore, the correct answer is carbon dioxide and water.
