All You Need to Know About Photosynthesis and Cellular Respiration

Photosynthesis and cellular respiration are the life processes that most organisms make to obtain the energy available from nature. Photosynthesis is done by most plants that can prepare their own food, but most animals respond to their energy demand through cellular respiration.

Photosynthesis is a process by which plant cells convert the light energy from the sun into chemical energy and produce enriched carbohydrate molecules such as glucose. Cell respiration is the process of degrading food molecules to obtain energy and storing them in the form of adenosine triphosphate (ATP) molecules.

After producing sugar molecules by photosynthesis, plant cells undergo cell respiration to produce ATP molecules. Animals obtain food molecules from plants and other organisms, and then perform cell respiration to obtain ATP molecules. All organisms use these stored ATP molecules for their metabolic processes

Photosynthesis takes place in two stages: photoreaction and dark reaction. Cell respiration is accompanied by aerobic (glycolysis) and anaerobic respiration

Photosynthesis occurs in the leaves of plants containing chlorophyll pigment. Cell respiration occurs in the cell cytoplasm and mitochondria

Photosynthesis uses sunlight to create food molecules. Cell respiration uses glucose molecules to obtain energy storage ATP molecules

Photosynthesis uses water from the atmosphere, sunlight, and carbon dioxide to produce glucose molecules and releases oxygen as a by-product. Cell respiration produces ATP molecules and carbon dioxide as by-products using glucose molecules and oxygen.

Photosynthesis involves converting one energy to another, ie, converting light energy into chemical energy. Cell respiration involves the use of this chemical energy and decomposition to release energy

Photosynthesis occurs only in plants and some bacteria. Cell respiration occurs in all kinds of organisms

Photosynthesis and cellular respiration are interdependent. Energy conversion that occurs in photosynthesis is used to promote reaction in cell respiration. Let's see an example. Grass is a plant that uses photosynthesis to make its own food. When it converts light energy into chemical energy in the form of glucose, glucose is used to form a new plant structure and the lawn grows. Outdoor cattle eat grass and break down glucose during cell respiration. The chemical energy contained in glucose is converted to ATP and used to power cows to grow alive.

Photosynthesis is the process of converting light energy into chemical energy in the form of glucose called chloroplast. Glucose produced by photosynthesis is then used during cell respiration. In cellular respiration, the energy stored in the binding of glucose molecules is resolved and converted to another type of energy ATP. Both photosynthesis and cellular respiration start with one energy and convert it to another energy, but the type involved is different. Photosynthesis uses light energy to create complex molecules in anabolic reactions, cell respiration breaks down these molecules and releases energy in catabolic reactions.

Photosynthesis and cellular respiration are similar, but they all require the input of energy and convert it to a usable form. In photosynthesis, the initial energy is in the form of light, and in cell respiration, the initial energy is stored in the chemical bond of glucose. Think about baking these processes. If you have flour, sugar, eggs and butter, you can call a variety of desserts. You can use these starting materials to make cakes, muffins and bread. Cell respiration and photosynthesis start with energy, but they end in various forms.
