Cellular metabolism is all about how our cells change food into energy. This energy is really important for growth and development in all living things! There are two main processes we need to know about: photosynthesis and cellular respiration.

1. Photosynthesis:

   • This process happens in plants and some bacteria.
   • They use sunlight to turn carbon dioxide and water into glucose (a type of sugar) and oxygen.
   • The glucose is super important because it provides energy for plants to grow.

2. Cellular Respiration:

   • This is how living things break down glucose to make energy.
   • It takes place in all living cells and can be summed up like this:
     • Glucose + Oxygen → Carbon Dioxide + Water + Energy (ATP)
   • ATP (adenosine triphosphate) is what we call the energy currency of the cell. It helps power many important processes that keep living things growing and functioning.

In short, these metabolic processes make sure that living things have the energy they need to grow, develop, and carry out their vital functions. Without these processes, life wouldn’t be as lively and exciting as it is!
