Question

Draw and label all the steps involved in aerobic respiration. draw arrows to explain each step. please do not write paragraphs.

Answer 1

.
Pyruvic acid + COA+NADt. Mq2+ → Acetyl LGA + CO₂ + NAOH + H+ Pyruvate dehydrogenase TRICARBOX YLIC ACID CYCLE / CITRIC ACID CYCLE | KREB'S CYCLE Acetyl coenzyme A (ac) Citric and (66) CO2 Oxaloacetic acid (40) INAOH + NAD NADH + H+ ol-keto glutaric acid (50) NAD MI TOCHONDRI Mallic acid (46) CO2 NAD FADH₂ ODP NADH+H Succinic acid (4c) FAD → OTP TE
Glycolysis or the EMP Pathway is common for both anaerobic and aerobic organisms. Glycolysis occurs in the cytoplasm of the cell. In this process glucose undergoes partial oxidation to form 2 molecules of pyruvic acid.

For areobic respiration to takes place pyruvic acid is transported from the cytoplasm to mitochondria. After it enters mitochondrial matrix it undergoes oxidative decarboxylation by a complex set of reaction and forms acetyl CoA which is catalysed by pyruvic dehydrogenase.

The acetyl CoA then enters a cyclic pathway called tricarboxylic acid cycle/ kreb's cycle /citric acid cycle for the complete oxidatikn of pyruvate. The complete oxidation of pyruvate by the stepwise removal of all hydrogen atoms.leaving three molecules of CO2. Tje passing on of the electrons remived as part of ghe hydrogen atoms to molecular O2 witb simultaneous synthesis of ATP .
