Photosynthesis in Higher Plants

Question

In which type of reactions related to plant photosynthesis peroxisomes are involved?

  • Glycolate cycle

  • Calvin cycle

  • Bacterial photosynthesis

  • Glyoxylate cycle

Answer

A.

Glycolate cycle

Peroxisome is a small organelle that is bounded by a single membrane. Peroxisome detoxify certain by-products of photosynthesis and oxidise glycolate (produced by photorespiration) to glyoxylate which can then be salvaged by a series of reactions involving mitochondria and chloroplasts as well as peroxisomes.
