Your friend asks for your help checking their essay about sugar production and use in plants. They have found an online encyclopedia that says the following. "Plants produce glucose via photosynthesis. Glucose is linked together to form the carbohydrate starch." Your friend is confused, though, because a university website states that "glucose is linked together to form cellulose, the main part of plant cell walls."

Help your friend fact check their information. In 3-5 sentences, describe how they can determine which website(s) to believe.

The rate of photosynthesis can be measured by examining the production of oxygen or the consumption of carbon dioxide. By measuring the amount of oxygen released or the amount of carbon dioxide consumed over a specific period of time, we can determine the rate at which photosynthesis is occurring. Similarly, the rate of cellular respiration can be measured by monitoring the consumption of oxygen or the production of carbon dioxide. By measuring the decrease in oxygen or the increase in carbon dioxide concentration, we can determine the rate at which cellular respiration is taking place.

The process of a substance dissolving in water and the temperature of the surroundings decreasing is indicative of an endothermic reaction. In an endothermic process, energy is absorbed from the surroundings, resulting in a decrease in temperature. When a substance dissolves in water, it requires energy to break the intermolecular forces holding the particles together. This energy is taken from the surroundings, causing a decrease in the temperature. Therefore, the decrease in temperature indicates that the dissolving process is absorbing heat, making it an endothermic reaction.

The nutrients in our diet play a crucial role in our body's biochemistry. Proteins, for example, are broken down into amino acids, which are used to build and repair tissues and serve as enzymes and hormones. Carbohydrates are converted into glucose, providing energy for cellular processes. Fats are broken down into fatty acids, which are utilized as a source of energy and for building cell membranes. Additionally, vitamins and minerals act as coenzymes and cofactors in various biochemical reactions. Overall, the nutrients we consume provide the essential building blocks and energy required for our body's biochemical processes to occur efficiently.
