2.glucose+oxygen= carbon dioxide+ water+energy
3. 2ATP per glucose
4. stems and roots
5.mitochondria
Answer:
1)Anaerobic respiration, also called fermentation as it occurs when cells need energy but there is no oxygen for aerobic respiration. As a result, cells convert glucose into either ethanol or lactic acid.
2)Aerobic respiration is the aerobic catabolism of nutrients to carbon dioxide, water, and energy, and involves an electron transport system in which molecular oxygen is the final electron acceptor. The overall reaction is: C6H12O6 + 6O2 yields 6CO2 + 6H2O + energy (as ATP).
3)Aerobic respiration produces 38 ATP whereas anaerobic respiration produces only 2 ATP molecules.
4)Lenticels are found as raised circular, oval, or elongated areas on stems and roots. In woody plants, lenticels commonly appear as rough, cork-like structures on young branches. Underneath them, porous tissue creates a number of large intercellular spaces between cells.
5)The complete glucose breakdown is a series of chemical reactions representing transformation of glucose to adenosine triphosphate during the normal phases of aerobic cellular respiration. It is mostly done inside the mitochondria to release the maximum amount of energy.
