Comparing & Contrasting Cellular Respiration & Photosynthesis | cypenv.info
Cellular respiration - - Photosynthesis and cellular respiration are complementary processes by Difference Between Words: English and Science Vocabulary. Covers relationship between cellular respiration and photosynthesis. Compare and contrast the major pathways of photosynthesis and respiration. Cellular respiration and photosynthesis are the two major processes by which animal and plant cells supply . What's the difference between speed and velocity?.
You might have already known some of that!
Keep this simple overview in mind as we explore both processes in more detail. The major inputs and outputs of respiration and photosynthesis and the link between humans and plants. Respiration and Photosynthesis Metabolism includes both the breakdown of molecules to obtain energy and the use of energy to build molecules.
Comparing & Contrasting Cellular Respiration & Photosynthesis
All living organisms carry out both parts of metabolism but here we are just focusing on two different kinds of metabolism: Like we saw in our simple overview, in many ways respiration and photosynthesis are the opposite of each other. Respiration breaks down molecules like sugar, fat, and protein, and captures their energy to do work inside the cell. In contrast, photosynthesis uses the energy of light from the sun to build sugars to be used for plant growth and energy.
Mitochondria and Chloroplasts Both respiration and photosynthesis occur in specialized compartments inside cells. Respiration occurs in mitochondria and photosynthesis occurs in chloroplasts. We usually think about respiration happening in animals and photosynthesis happening in plants but really it isn't that simple.
While all animals use respiration, plants use both photosynthesis and respiration. And, there are microorganisms that are capable of both processes!
Metabolic Pathways A metabolic pathway is a group of enzymes that work one after another to build or break down a molecule. Several different factors influence the process of photosynthesis including: The process of photosynthesis is stimulated by high concentrations of carbon dioxide in the atmosphere.
Photosynthesis is slowed down when transpiration is reduced. In order to absorb carbon dioxide, plants must transpire.

When water is scarce, transpiration is reduced, resulting in photosynthesis being slowed down. The plants physiology will slow down when the temperature dips below zero degrees Celsius, resulting in photosynthesis stopping. Understanding Cellular Respiration Cellular respiration is a process in which water and carbon dioxide are produced through the break down of chemical bonds of glucose or the oxidizing of food molecules.
Energy is released during cellular respiration and is captured as Adenosine Triphosphate ATP and then utilized by different cell activities that consume energy. Aerobic respiration and glycolysis are the two main steps responsible for completely breaking down glucose into water and carbon dioxide. This process, at which point the pyruvate molecules created during glycolyis, breaks down further when there is oxygen and creates 34 ATP molecules.
This anaerobic catabolism of glucose produces two ATP molecules and two pyruvate molecules, and happens in all cells. There are a few key differences between cellular respiration and photosynthesis.
This process involves plants making food by using sunlight. In order to produce glucose, this process requires energy. This process occurs in some bacteria and in all plants. This process occurs within the chloroplasts, the chlorophyll-containing organelles inside a plant.Photosynthesis & Respiration
In order to release oxygen back into the atmosphere and create sugar, this process requires water, sunlight, and carbon dioxide from the atmosphere. This process converts the food created by photosynthesis into energy which is then utilized by living organisms and plants.
