WebOct 4, 2024 · C4 has one step in the pathway before the Calvin Cycle which reduces the amount of carbon that is lost in the overall process. The carbon dioxide that is taken in by the plant is moved to bundle sheath cells by the malic acid or aspartic acid molecules (at this point the molecules are called malate and aspartate). WebThe Calvin Cycle in bundle sheath cells is just the same as the Calvin Cycle in C3 plants, so I think the Calvin Cycle does occur in chloroplasts in the bundle sheath cells. The diagrams in the following website suggest this: …
