This should be correct, but it is not a 100% guarantee on my part.
Answer:
Explanation:
Photosynthesis is a special process that certain organisms (plants, algae, and some bacteria) undergo to create "food".
This turns light energy, carbon dioxide, and water into glucose and oxygen. The glucose becomes the food for the organism, because it is turned into ATP during cellular respiration. The ATP is energy that fuels the processes, like growth, repair, and transport.
This process occurs because of the <u>sun</u>. It provides the light energy needed for the reaction. Organelles inside of the cells, called chloroplasts, contain a pigment (chlorophyll) that captures this energy.
The correct answer is A. the change in pH affects the shape and function of the enzyme. It can only function properly in its optimal pH range.
Enzymes are protein molecules and they have a specific shape, which is altered by temperatures and pH that are not within the enzyme's range of operation. This is because the temperature and pH alter the enzyme's structure, which means the shape of its active site is changed and its substrate is not able to fit inside the active site of the enzyme molecule.
