Tricarboxylic acid cycle end products

• The conversion of succinyl CoA to succinate generates one ATP.
• In the following reactions, 3 NAD+ are reduced to NADH and 1 FAD+ is converted to FADH2:

NADH Isocitrate to -ketoglutarate -ketoglutarate to succinyl CoA NADH Succinate to fumarate FADH2 Malate to Oxaloacetate NADH

• Two molecules of CO2 are emitted. CO2 removal or citric acid decarboxylation occurs in two locations:

Isocitrate (6C) is being transformed into -ketoglutarate throughout this procedure (5C)
When -ketoglutarate (5C) is turned into succinyl CoA (4C)

• Two cycles are needed for every glucose molecule because oxidative decarboxylation of two pyruvates results in the production of two acetyl CoA molecules.
• Each NADH molecule can generate 1-2 ATPs upon oxidation in the electron transport chain, whereas each FADH2 molecule only generates 2 ATPs.
• To summarise, the Krebs cycle produces 4 CO2, 6NADH, 2 FADH2, and 2 ATPs for the complete oxidation of a glucose molecule.

Plants respire throughout their lives because the plant cell requires energy to survive; however, plants breathe in a unique way known as cellular respiration. Photosynthesis is the process by which plants generate glucose molecules by capturing and converting sunlight energy. Several live experiments demonstrate plant respiration. All plants respire in order to provide energy to their cells, allowing them to be active or alive. 

Plants require oxygen to respire, and the process emits carbon dioxide. However, plants do have stomata (found in leaves) and lenticels (found in stems) that are actively involved in gas exchange. Plants lack specialized structures for gas exchange, in contrast to people and other creatures. Plant leaves, stems, and roots respire at a slower rate than other parts of the plant.
