Description of photosynthesis and respiration

photosynthesis and respiration worksheet answers

Without it, life on Earth would cease to exist. Respiration occurs in your cells and is fueled by the oxygen you inhale. In the mesophyll cells, the hydration of carbon dioxide produces a bicarbonate ion in the presence of carbonic anhydrase.

Through these processes, plants obtain the carbon dioxide they need and living organisms obtain the oxygen they need.

It does not require the presence of sunlight and is always occurring in living organisms. In the bundle sheath cells in the chloroplast of these cellsmalate is converted to a 3 carbon pyruvate following the removal of CO2 through decarboxylation this reaction produces CO2, pyruvate, and NADPH.

Difference between photosynthesis and respiration

Like solar panels, leaves, for the most part, are thin and broad with the broad part of the leaf facing the sun. For this reason, C4 plants do not necessarily need to have their stomata open to absorb more carbon dioxide for photosynthesis. Oxygen is also formed. Through these processes, plants obtain the carbon dioxide they need and living organisms obtain the oxygen they need. Plants burn energy as they grow, too. C4 Cycle In C4 plants pineapple, corn, and sugarcane among others the photosynthesis takes place in the mesophyll and bundle sheath cells. The ATP molecule can then be transported throughout the cell where its stored energy is used to complete various tasks within the cell. Here, CO2 diffuses into the stroma where sugar is synthesized. In the stroma, the enzyme ribulose bisphosphate carboxylase catalyzes a reaction between the gas CO2 and three molecules of a five-carbon acceptor known as ribulose bisphosphate RuBP.

This ensures that sufficient light energy is collected for photosynthesis. Cellular respiration uses glucose and oxygen to produce carbon dioxide and water.

How are photosynthesis and cellular respiration related

C4 Cycle In C4 plants pineapple, corn, and sugarcane among others the photosynthesis takes place in the mesophyll and bundle sheath cells. This glucose can be converted into pyruvate which releases adenosine triphosphate ATP by cellular respiration. During daytime, photosynthesis produces oxygen and glucose faster than respiration consumes it. Through these processes, plants obtain the carbon dioxide they need and living organisms obtain the oxygen they need. Oxygen is also formed. Plants then store the potential energy in the form of biomass biological matter that fuels nearly every animal on earth. As you can see, thanks to these two life-sustaining processes, plants and animals depend on each other to survive. In essence, this process transforms a wave of light energy into chemical potential energy, which the plant then stores in the molecular bonds of sugar molecules. Cottonwood trees, for example, will lose gallons about dm3 of water per hour during hot desert days. During respiration, plants consume nutrients to keep plant cells alive while during photosynthesis, plants create their own food. In this case, then, rubisco serves as a carboxylase that plays an important role in reducing photorespiration. Dim sunlight — Photosynthesis rate equals respiration rate. Cellular respiration uses glucose and oxygen to produce carbon dioxide and water.
