Verified step by step guidance
1
Understand the process of cellular respiration, which is a series of metabolic reactions that convert biochemical energy from nutrients into adenosine triphosphate (ATP), and release waste products.
Identify the main stages of cellular respiration: glycolysis, the citric acid cycle (Krebs cycle), and oxidative phosphorylation. Each stage contributes to the production of ATP.
Recognize that ATP (adenosine triphosphate) is the primary energy carrier in cells, providing energy for various cellular processes.
Differentiate between ATP and other molecules involved in cellular respiration, such as NADH and glucose. NADH is an electron carrier that plays a role in transferring electrons to the electron transport chain, while glucose is the initial substrate that is broken down to release energy.
Conclude that ATP is the primary energy molecule produced during cellular respiration, as it is the direct source of energy for cellular activities.
