The glycolate produced diffuses into the membrane bounded organelles called____________?

Correct answer: B. Peroxisomes

  • A. Glyoxisomes
  • B. Peroxisomes
  • C. Lysosomes
  • D. Mitochondria

Explanation

Glycolate formed during photorespiration diffuses into peroxisomes, where it is oxidized and converted into compounds that continue the photorespiratory pathway. Students may choose glyoxisomes because the name resembles peroxisomes, but glyoxisomes are specialized mainly for handling fats in germinating seeds.

About Cellular Respiration

Cellular respiration releases energy from glucose through glycolysis, the link reaction, the Krebs cycle and the electron transport chain, producing ATP. The pathway differs in oxygen availability: aerobic respiration uses oxygen and yields more ATP, while anaerobic respiration produces much less ATP and forms lactic acid in muscles or ethanol and carbon dioxide in yeast.
