Match each respiratory process with its corresponding characteristic end-products.

  • GlycolysisPyruvate, ATP, and NADH
  • Krebs cycleCarbon dioxide, ATP, NADH, and FADH2
  • Electron transport chainWater and a high yield of ATP
  • Alcoholic fermentationEthanol, carbon dioxide, and ATP

Cevap

Glycolysis matches with Pyruvate, ATP, and NADH; Krebs cycle matches with Carbon dioxide, ATP, NADH, and FADH2; Electron transport chain matches with Water and a high yield of ATP; Alcoholic fermentation matches with Ethanol, carbon dioxide, and ATP.
Each respiratory metabolic pathway yields distinct chemical end-products. Glycolysis yields pyruvate, ATP, and NADH. The Krebs cycle produces carbon dioxide, ATP, NADH, and FADH2. The electron transport chain synthesizes water and a high yield of ATP. Alcoholic fermentation produces ethanol, carbon dioxide, and ATP.

Adım Adım Çözüm

1
Identify the primary end-products of glycolysis.
Glycolysis splits one glucose molecule into two pyruvate molecules while producing net 2 ATP2\text{ ATP} and 2 NADH2\text{ NADH}.
This represents the initial cytoplasm-based stage of glucose degradation.
2
Identify the main products of the Krebs cycle.
The breakdown of acetyl-CoA in the mitochondrial matrix releases CO2\text{CO}_2 along with reduced electron carriers (NADH and FADH2) and ATP.
This accounts for the complete decarboxylation and oxidation of carbon intermediates.
3
Determine the output of the electron transport chain.
Electrons passed to oxygen form H2O\text{H}_2\text{O}, driving oxidative phosphorylation to generate the bulk of ATP.
Oxygen serves as the final electron acceptor in aerobic respiration.
4
Match anaerobic alcoholic fermentation with its characteristic products.
In yeast, anaerobic pathway breakdown yields ethyl alcohol (ethanol), carbon dioxide gas, and ATP.
Fermentation regenerates NAD+ necessary to keep glycolysis operational without oxygen.
