Triose Phosphate That Leaves the Calvin Cycle Builds Every Carbon Compound a Plant Needs

The Calvin cycle makes triose phosphate (TP), the three-carbon sugar that feeds the rest of the plant's chemistry.
The triose phosphate that leaves the cycle is a versatile building block for many carbon compounds, not just glucose.
To build compounds that also contain nitrogen, sulfur or phosphorus, the plant adds mineral nutrients taken up from the soil.

Exam technique

You are not required to know the detailed steps of these synthesis pathways.
You should know that almost every carbon compound in a plant can be traced back to triose phosphate.

One Product, Many Uses: What Triose Phosphate Becomes

Note

Only the triose phosphate that is not needed to regenerate RuBP is free to make products.
That spare triose phosphate is the starting material for the compounds below.

The Main Products Made From Triose Phosphate

Carbohydrates: two triose phosphate join to form hexose sugars such as glucose.
1. Glucose is joined into starch for storage or cellulose for cell walls.
2. It can also be converted into sucrose for transport around the plant.
