In the context of cellular respiration, which term refers to the amount of energy left after cellular respiration has occurred?

• A. Photosynthetic yield
• B. Primary production
• C. Net production
• D. Gross production

Answer: (C)

Verified step by step guidance

1. Step 1: Understand the context of cellular respiration. Cellular respiration is the process by which cells convert glucose and oxygen into energy (ATP), carbon dioxide, and water. It involves multiple stages, including glycolysis, the Krebs cycle, and oxidative phosphorylation.
2. Step 2: Define the terms provided in the problem. For example: 'Photosynthetic yield' refers to the energy produced during photosynthesis, not cellular respiration. 'Primary production' is a term used in ecology to describe the rate at which plants and other photosynthetic organisms produce organic compounds. 'Gross production' refers to the total energy produced before any losses, while 'Net production' accounts for energy losses (e.g., through respiration).
3. Step 3: Relate the concept of 'Net production' to cellular respiration. Net production is the amount of energy left after accounting for the energy used during cellular respiration. It represents the usable energy available for the organism after subtracting the energy expended.
4. Step 4: Eliminate incorrect options based on their definitions. Since 'Photosynthetic yield' and 'Primary production' are unrelated to cellular respiration, and 'Gross production' does not account for energy losses, the correct term is 'Net production.'
5. Step 5: Conclude that 'Net production' is the term that refers to the amount of energy left after cellular respiration has occurred, as it accounts for the energy used during the process.
