Answer:

A. C-1

Explanation:

During the pentose phosphate pathway, glucose 6-phosphate is first converted into 6-phosphoglucono-lactone in the reaction catalyzed by glucose 6-phosphate dehydrogenase. The 6-phosphoglucono-lactone is then converted into 6-phospho-gluconate which in turn undergoes decarboxylation to form D-ribulose 5-phosphate and the C-1 of original glucose 6-phosphate is released in form of CO2.  

Therefore, to observe the most rapid production of labeled carbon atom in form of CO2, the C-1 of glucose should be labeled.

In ponds where it lives, the northern leopard frog is probably a significant indicator of the water's quality. This species is an essential component of the food chain, and tadpoles, which are the main eaters of algae in ponds, can have a big impact.

<h3>What distinguishes tree frogs from other frog species?</h3>

These frogs are most easily recognized by their feet, which have claw-shaped toe bones as their last bone. They can also climb trees thanks to toe pads with small suction cups and extraskeletal structures on their toes. They are available in a number of hues, the most popular being green, gray, or brown.
