Which of the following enzymes exist in both plants and animalsGroup of answer choicesphosphoribulokinaseribulose bisphosphate carboxylasesedoheptulose aldolasesedoheptulose bisphosphatasenone of the above

To determine which enzymes exist in both plants and animals, we need to analyze the given options:

1. Phosphoribulokinase: This enzyme is involved in the Calvin cycle, which is specific to plants. Therefore, it is not found in animals.

2. Ribulose bisphosphate carboxylase: This enzyme, also known as Rubisco, is a key enzyme in the Calvin cycle and is found in both plants and some bacteria. However, it is not present in animals.

3. Sedoheptulose aldolase: This enzyme is involved in the pentose phosphate pathway, which is present in both plants and animals. Therefore, it exists in both.

4. Sedoheptulose bisphosphatase: This enzyme is also involved in the pentose phosphate pathway and is found in both plants and animals.

Based on the analysis, the enzymes that exist in both plants and animals are sedoheptulose aldolase and sedoheptulose bisphosphatase.
