Knowing how photosynthesis is related to cellular respiration will help you understand why these two biochemical reactions are important for survival of life on. The necessary reactants for cellular respiration are Glucose and Oxygen, which are the waste products of photosynthesis. The products from. The ecosystems of the world are generally in balance with one another. Animals and plants live in mutually beneficial relationships. We will.
Become a Contributor How is Photosynthesis Related to Cellular Respiration Knowing how photosynthesis is related to cellular respiration will help you understand why these two biochemical reactions are important for survival of life on the Earth. Continue reading for more information on photosynthesis and cellular respiration, with special emphasis on the relationship between the two. BiologyWise Staff Photosynthesis and cellular respiration are two biochemical reactions which have a crucial role to play when it comes to life on the planet Earth.
While photosynthesis is a process wherein plants absorb energy directly from the Sun to prepare their own food, cellular respiration refers to the process wherein the energy that is stored in plants in the form of glucose is used by organisms for their own survival. The basic rule that energy cannot be created or destroyed, but can only be transferred from one form to another is applicable to either of these biochemical reactions.
Photosynthesis and Cellular Respiration While plants and animals both resort to respiration, photosynthesis is only restricted to green plants and few other organisms.
This - however, doesn't mean that the latter is only useful for plants and other organisms which are directly involved. Both these processes are important for all the lifeforms on the planet - either directly or indirectly, as they are related to each other. In order to understand how photosynthesis is related to cellular respiration, one has to get well-versed with the basics of each of them.
What is the relationship between photosynthesis and cellular respiration?
Photosynthesis is a process wherein synthesis of sugar glucose is carried out using sunlight which acts as the radiant energycarbon dioxide and water. The electrons are then passed to the inner mitochondrial membrane. This membrane is loaded with specialized proteins, capable of transferring energy derived from the passing of electrons down their potential gradient.
This electron transport chain uses a series of electron driven enzymes, which specialize in binding loose phosphate groups to ADP.
In doing so, they store energy in the bond between these molecules, and create an ATP. These ATP molecules are then exported from the mitochondria, and can be used throughout the cell to provide energy in other reactions. For instance, ATP is used to pump ions out of cells, creating the electrical potential needed for nervous reactions.
There are innumerous other examples. However, there is a large body of evidence which points to the fact that all life has a common ancestor. This ancestor then diverged, over hundreds of millions of years, into the millions of species we see on Earth today.
The process of endosymbiosis would account for this complexity. Bacteria, the simplest organisms, likely represent a fairly unchanged version of the first form of life.
Bacteria have no organelles, and complete all the reactions they need for metabolism within a single compartment. Many bacteria are able to complete glycolysis, which can provide them with energy. Others are able to photosynthesize, like primitive single-celled plants. According to Endosymbiotic theorythese ancient bacteria began interacting and the processes of evolution drove them into different niches within the environment.
Some would harness sunlight, while others would feed upon those. Eventually, some of the predatory bacteria became quite large. As such, they could take in large quantities of smaller bacteria. Instead of digesting them, they created a safe space for them and helped them produce more energy. Thus, the smaller endosymbiotic bacteria became the first organelles. This theory suggests that chloroplasts were originally photosynthetic bacteria, and that mitochondria were originally bacteria capable of oxidative phosphorylation.
The larger bacteria became eukaryotes, and developed other organelles. This theory is backed by the evidence that both chloroplasts and mitochondria are surrounded in double membranes, a supposed remnant of the ancestral engulfing process. Further, both mitochondria and chloroplast contain bits of circular DNA, similar to that found in bacteria. Cellular Respiration, Photosynthesis, and Ecology Hundreds of millions of years after this division of organelles, and evolution has given us what we see today.
Plants are related to algae, which are related to photosynthetic bacteria. Animals are related to the ancient organisms which did not receive photosynthetic endosymbionts, and instead relied on consuming other organisms. At the bottom of the food-chain sit the photosynthetic organisms. They form by far the largest biomass on Earth, limited only by the amount of sunlight, nutrients, and water they receive. One step above plants and algae, herbivores exploit the bounty that plants produce.
Some of the largest animals in the world, such as the elephant, are entirely herbivorous. But, there are herbivores of every size, all the way down to grasshoppers and tiny insects. Because an herbivore must consume many photosynthetic organisms to grow, there are many less organisms on this level of the food-chain.
Likewise, there are many less carnivores than there are herbivores, because they must feed on many smaller organisms throughout their life to grow and reproduce.
In this way, the entire food-chain and ecology in general is entirely based off of the processes of photosynthesis and cellular respiration. Ecology is also the study of how various organisms interact with each other while carrying out these reactions.
Which of the following is NOT a difference between photosynthesis and cellular respiration A.
Relationship Between Photosynthesis and Cellular Respiration by Paul Wilkinson on Prezi
Only one uses sunlight B. Only one breaks glucose down C. Only one relies on a cycle of carbon molecules Answer to Question 1 C is correct. The Krebs cycle and the Calvin cycle, while differing in their outputs, both rely on a chain of carbon molecules which are continually recycled.
The molecules are different, but the processes are very similar. As a human, your cells rely on glucose to function. Where does this glucose come from?
Meat Answer to Question 2 B is correct. All of the food that you consume was at one point a plant.
If you eat meat, the nutrients you receive from that meat are the same nutrients that animal ate before it died. Even the protein and fat in animals is simply a reuse of the protein and glucose found in plants. Which of the following things would be MOST devastating to an ecosystem? All the grass in a meadow is killed with an herbicide. All the butterflies in a meadow are killed with a pesticide.
All the birds in a meadow are killed by hunters. Answer to Question 3 A is correct.
