Question

the enzyme that attaches the molecule of carbon dioxide to the 5 - carbon molecule rubp is called

• rubisco is sometimes referred to as the \bridge\ or \gateway\ to life, because carbon dioxide is considered a lifeless molecule, but rubp is organic and part of the plants cellular processes.

Explanation:

The question is about the enzyme in the Calvin Cycle (a part of photosynthesis) that attaches \(CO_2\) to RuBP. As per the provided text and biological knowledge, Rubisco (Ribulose - 1,5 - bisphosphate carboxylase/oxygenase) is the enzyme for this reaction. The text also gives context about Rubisco being called a “bridge” or “gateway” to life, which aligns with its role in carbon fixation (attaching inorganic \(CO_2\) to organic RuBP).

Answer:

Rubisco
