Similarly, we might think of plants using carbon dioxide and sunlight for photosynthesis and producing oxygen and ... The hydrogen ion (produced when carbonic acid decomposes) LOWERS the pH of the ...

Scientists design bioinspired hydrogels that mimic plant photosynthesis for clean hydrogen energy production. A new hydrogel ...

Artificial photosynthesis, which mimics nature’s process of converting ... the potential of hydrogen ions (pH), light, and ...

This process, called photosynthesis, is essential to the global carbon cycle and organisms that conduct photosynthesis represent the lowest level in most food chains (Figure 1). Most living things ...

In this instance, the dependent variable, what you're measuring, is the rate of change of pH in the solution. As photosynthesis occurs, carbon dioxide levels decrease. As carbon dioxide is an ...

Independent variable - pH level Dependent variable - Time taken for starch to be broken down. Control variables - Temperature, volume and concentrations of enzyme solution and starch solution.
