Classify each of the following as exothermic or endothermic:c. The metabolism of glucose in the body provides energy.

Verified step by step guidance

1. Understand the terms: Exothermic processes release energy, usually in the form of heat, while endothermic processes absorb energy.
2. Consider the context: Metabolism is a series of chemical reactions in the body that convert food into energy.
3. Identify the process: The metabolism of glucose involves breaking down glucose molecules to release energy.
4. Relate to energy flow: Since the metabolism of glucose provides energy, it indicates that energy is being released.
5. Classify the process: Based on the release of energy, classify the metabolism of glucose as an exothermic process.

Key Concepts

Exothermic Reactions

Exothermic reactions are chemical processes that release energy, usually in the form of heat, to their surroundings. This occurs when the total energy of the products is lower than that of the reactants, resulting in a net release of energy. Common examples include combustion and respiration, where energy is produced and can be harnessed for biological functions.

Endothermic Reactions

Endothermic reactions absorb energy from their surroundings, leading to a decrease in temperature in the immediate environment. In these reactions, the energy of the products is higher than that of the reactants, requiring an input of energy to proceed. Photosynthesis is a classic example, where plants absorb sunlight to convert carbon dioxide and water into glucose.

Metabolism of Glucose

The metabolism of glucose is a series of biochemical reactions that convert glucose into energy, primarily through cellular respiration. This process is exothermic, as it releases energy stored in glucose molecules, which is then used by cells for various functions. The overall reaction can be summarized as glucose reacting with oxygen to produce carbon dioxide, water, and energy.
