1. Sugar
2. ATP
3.carbon dioxide
4. water
Thank you!

Answer 1

The molecule that provides the activation energy that starts glycolysis is **ATP**. In the initial steps of glycolysis, ATP is used to phosphorylate glucose and convert it into glucose-6-phosphate, which helps to initiate the pathway. So, the correct answer is:

2. ATP
