- Like cellular respiration, photosynthesis also uses an electron transport chain to make a H + concentration gradient, which drives ATP synthesis by chemiosmosis.

Aug 9, 2024 · Photosynthesis is the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.

The process of photosynthesis occurs in a middle layer called the mesophyll. The gas exchange of carbon dioxide and oxygen occurs through small, regulated openings called stomata (singular: stoma), which also play roles in the regulation of gas exchange and water balance.
All organisms, including humans, need energy to fuel the metabolic reactions of growth, development, and reproduction. But organisms can't use light energy directly for their metabolic needs. Instead, it must first be converted into chemical energy through the process of photosynthesis.

Jul 30, 2017 · Photosynthesis is the biochemical pathway which converts the energy of light into the bonds of glucose molecules. The process of photosynthesis occurs in two steps. In the first step, energy from light is stored in the bonds of adenosine triphosphate (ATP), and nicotinamide adenine dinucleotide phosphate (NADPH).
The three major functions that are basic to plant growth and development are: using chlorophyll to capture light energy and convert it to energy stored in sugars. Photosynthesis uses light energy, arbon dioxide (CO2), and water (H2O) to generate glucose with a byproduct. Transpiration – The loss of water vapor through the stomates of leaves.

During the process of photosynthesis, cells use carbon dioxide and energy from the Sun to make sugar molecules and oxygen. These sugar molecules are the basis for more complex...
Key points: Many organisms make their own food through photosynthesis. Plants, algae, and some unicellular organisms do photosynthesis. Photosynthesis is powered by energy from sunlight. This energy is used to rearrange atoms in carbon dioxide and water to make oxygen and sugars. Carbon dioxide and water are inputs of photosynthesis.
