Two essential biological processes are cellular respiration and photosynthesis. Cellular respiration, which takes place in the cytoplasm of prokaryotes and mitochondria of eukaryotes, transforms oxygen (O₂) and glucose (C₆H₁₂O₆) into ATP, carbon dioxide (CO₂), and water (H₂O). It includes the electron transport pathway, the Krebs cycle, and glycolysis. On the other hand, photosynthesis takes place in chloroplasts, where light energy is used to transform CO₂ and water into glucose and O₂ through the Calvin Cycle and other light-dependent processes. Carbon is moved through photosynthesis and respiration as part of the global carbon cycle. Deforestation and the combustion of fossil fuels are two examples of human actions that upset this cycle, raising CO2 levels and causing climate change. This has an effect on cellular respiration and plant photosynthesis, which in turn impacts ecosystem health and energy output.

Answer 1

Cellular respiration and photosynthesis are two really important processes that happen in living things.

Cellular respiration happens in tiny cell parts called mitochondria in plants and animals, and in the cytoplasm of simple cells called prokaryotes. In this process, cells use oxygen (O₂) and a sugar called glucose (C₆H₁₂O₆) to make energy, called ATP, and they also make carbon dioxide (CO₂) and water (H₂O). It has three main steps: glycolysis, the Krebs cycle, and the electron transport chain.

Photosynthesis is how plants make their food. It happens in little green structures called chloroplasts. Plants take in carbon dioxide (CO₂) from the air and water (H₂O), and with the help of sunlight, they turn these into glucose (which is like their food) and oxygen (O₂). This process includes something called the Calvin Cycle and steps that need sunlight.

Both of these processes are part of the global carbon cycle, which is how carbon moves all around our planet. But humans can mess this up! Cutting down forests (deforestation) and burning fossil fuels (like coal and oil) release lots of CO₂ into the air. This extra carbon dioxide can lead to climate change. Climate change can affect how well plants can photosynthesize and how well animals and humans can do cellular respiration. All these changes can hurt our ecosystems and how energy flows in nature.
