003 What ATP is and How it Works

The video explains ATP, a molecule crucial for energy transfer in cells. It describes ATP's structure, its role as the body's energy currency, and how it releases energy by breaking phosphate bonds. The video also covers how ATP provides energy to cellular processes and the cycle of recharging ATP in the mitochondria, likening it to a rechargeable battery. The importance of ATP in everyday activities is highlighted.

What is the primary role of ATP in the cell?

• To provide structural support

• To store genetic information

• To act as the energy currency

• To transport oxygen

What happens when the bond between two phosphate groups in ATP is broken?

• ATP is converted to glucose

• Energy is released

• ATP becomes a protein

• Energy is absorbed

What does ATP donate to a process or protein to provide energy?

• A glucose molecule

• A hydrogen atom

• A phosphate group

• An electron

What is ATP converted into after it donates a phosphate group?

• GTP

• NADH

• ADP

• AMP

Which organelle is responsible for recharging ADP back into ATP?

• Mitochondria

• Ribosome

• Chloroplast

• Nucleus
