Rubisco is a very slow enzyme

Reference no: EM137052

Q1. Data suggest that rubisco (ribulose-1, 5-bisphosphate carboxylase) makes up 10 percent of the total protein found in spinach leaves. Research elucidating the structure of rubisco shows that it has four active sites. Why, with four active sites, might there be such a large concentration of rubisco in plant matter?

Rubisco catalyzes four of the six reactions found in the Calvin cycle.

Three of four active sites bind carbon dioxide; only one binds ribulose-1, 5-bisphosphate.

Rubisco is a very slow enzyme; what it lacks in speed, it makes up in numbers.

All heterotrophic organisms depend on plants, either directly or not directly, for their food supply.

Q2. What is anatomical variation of the GIT of carnivores, omnivores and non-ruminant herbivores and relate morphological variations with their diet and environment.
