7. Respiration in Plants
Respiration is a vital biochemical process through which plants convert glucose into energy. This process occurs continuously via aerobic and anaerobic respiration and consists of various phases including glycolysis, the Krebs cycle, and fermentation. The interconnectedness of respiration and photosynthesis highlights the role of these processes in sustaining plant life and energy dynamics in ecosystems.

What we have learnt
- Respiration is crucial for energy production in plants.
- There are two main types of respiration: aerobic and anaerobic.
- Respiration occurs in all parts of the plant, including roots, stems, and leaves.
Key Concepts
- -- Aerobic Respiration
- A type of respiration occurring in the presence of oxygen, producing a large amount of ATP.
- -- Anaerobic Respiration
- A type of respiration occurring in the absence of oxygen, producing smaller amounts of ATP and byproducts like alcohol or lactic acid.
- -- Glycolysis
- The initial step in glucose breakdown, producing pyruvate and releasing energy in the form of ATP and NADH.
- -- Krebs Cycle
- A series of reactions in the mitochondria that fully oxidizes acetyl-CoA to carbon dioxide, producing NADH and FADH2.
- -- Fermentation
- An anaerobic process that allows ATP production without oxygen, resulting in byproducts such as lactic acid or ethanol.
