Aerobic respiration how many atp

Enough energy is released from each pyruvate molecule to produce a large number of ATP molecules. As in stage one, the breakdown reactions in this process are catalysed by specific enzymes. Oxygen does not react directly with molecules of pyruvate. It is involved in the final step of the breakdown. A typical gymnospermous plant has 8 chromosomes in leaf cells.

What will be number of chromosomes in the cells of the gametophyte? Plant cell differs from animal cell in having Cell : The Unit of Life. Tonoplast is the membrane which surrounds Cell : The Unit of Life. Which of the following cell organelles are called suicide bags? Cell : The Unit of Life. Questions from Respiration in Plants.

Although most of the ATP results from oxidative phosphorylation and the electron transport chain ETC , 4 ATP are gained beforehand 2 from glycolysis and 2 from the citric acid cycle. The ETC is embedded in the inner mitochondrial membrane and comprises four main protein complexes and an ATP synthase. This distribution of protons generates a concentration gradient across the membrane. Four protons are needed to synthesize 1 ATP.

Since a single NADH produces 2. Importantly, glycolysis occurs in the cytosol and the ETC is located in the mitochondria in eukaryotes. The mitochondrial membrane is not permeable to NADH, hence the electrons of the 2 NADH that are produced by glycolysis need to be shuttled into the mitochondria.

Given the different ATP yield depending on the electron carrier, the total yield of cellular respiration is 30 to 32 ATP per glucose molecule.
