Question

The diagram is a representation of part of a plant cell. Identify the locations where proton concentration builds up during photosynthesis and cellular respiration.

Answer 1

The process of cellular respiration is achieved in plants by the process of photosynthesis. The energy from glucose is derived in this process. The steps of the cellular respiration includes the glycolysis, the kreb's cycle, and the oxidative phosphorylation. During this process, the proton concentration builds in the thylakoid space of the plant cell.

Answer 2

The eukaryotic cell with the cell wall and capable of producing food are called plant cells. They are the cells that have chloroplast and chlorophyll that helps them in making food.

During photosynthesis and cellular respiration processes, the proton concentration builds up in the thylakoid spaces.

The proton concentration can be explained as:

• Photosynthesis is food and energy-producing reaction that occurs in the presence of chlorophyll in chloroplast and cellular respiration is a method of utilizing the energy for the metabolic process and occurs in the mitochondria of the cell.

• The protons accumulate in the thylakoid which is a space present in the chloroplast when the process of glycolysis, TCA and oxidative phosphorylation takes place.

Therefore, the proton accumulates in the thylakoid.
