How do photosynthesis and cellular respiration compare?
How do photosynthesis and cellular respiration compare?
Differences between Cellular Respiration and Photosynthesis
| Cellular Respiration | Photosynthesis |
|---|---|
| In this process, food particles are broken down to release energy. | In this process, food is synthesized by capturing energy. |
| It is an exergonic reaction as energy is released. | It is an endothermic reaction as it requires energy. |
What is Photoexcitation crash course?
What is photoexcitation? electrons getting energy and not having anywhere to put it.
What is cellular respiration crash course?
Cellular respiration is how we derive energy from the food that we eat, specifically from glucose since most of what we eat ends up as glucose. First, our bodies have to turn that energy into a really specific form of stored energy called ATP, or adenosine triphosphate. You’ve heard me talk about this before.
What is happening during cellular respiration and photosynthesis?
Photosynthesis converts carbon dioxide and water into oxygen and glucose. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.
What two stages does cellular respiration occur?
Cellular respiration occurs in three stages: glycolysis, the Krebs cycle, and electron transport. Glycolysis is an anaerobic process. The other two stages are aerobic processes. The products of cellular respiration are needed for photosynthesis, and vice versa.
What comes first ps1 or ps2?
Though the two photosystems in the light-dependent reactions got their name in the series, they were discovered, but the photosystem II (PS II) comes first in the path in the electron flow and then the photosystem I (PSI).
What type of cellular respiration requires oxygen?
Aerobic
Key Terms
| Term | Meaning |
|---|---|
| Aerobic | Process that requires oxygen |
| Anaerobic | Process that does not require oxygen |
| Fermentation | An anaerobic pathway for breaking down glucose |
What are the 3 main parts of cellular respiration?
The transition from glucose to ATP doesn’t take place all at once, though. Cellular respiration is made up of three sub-processes: glycolysis, the Citric Acid Cycle (Krebs Cycle), and the Electron Transport Chain (ETC). Let’s talk about each one in detail.
What two places do cellular respiration occur?
Cellular respiration takes place in both the cytosol and mitochondria of cells. Glycolysis takes place in the cytosol, whereas pyruvate oxidation, the Krebs cycle, and oxidative phosphorylation occur in the mitochondrion. Figure 1 shows the locations of the main biochemical reactions involved in cellular respiration.
Where does respiration and cellular respiration occur?
Key Terms
| Term | Meaning |
|---|---|
| Mitochondria | The eukaryotic cell structure where cellular respiration occurs |
| Cytoplasm | The contents of a cell between the plasma membrane and the nuclear envelope; includes cytosol which is the jelly-like substance that fills the space between organelles |
| Aerobic | Process that requires oxygen |
Which is Crash Course Biology describes cellular respiration?
In which Hank does some push ups for science and describes the “economy” of cellular respiration and the various processes whereby our bodies create energy in the form of ATP. Crash Course Biology is now available on DVD! http://dftba.com/product/1av/CrashCou… Like CrashCourse on Facebook: http://www.facebook.com/YouTubeCrashC…
How are the steps of cellular respiration broken down?
Cell respiration can be broken down into five different steps: glycolysis, formation of acetyl COA, Krebs cycle, oxidative phosphorylation and chemiosmosis. 1. Glycolysis and Formation of Acetyl COA The first step in the essential AP® Biology concept of cellular respiration is glycolysis, which is a simple reaction that moves in a linear chain.
Where can I watch the crash course Biology?
Hank explains the extremely complex series of reactions whereby plants feed themselves on sunlight, carbon dioxide and water, and also create some by products we’re pretty fond of as well. Crash Course Biology is now available on DVD! http://dftba.com/product/1av/CrashCou… Like CrashCourse on Facebook: http://www.facebook.com/YouTubeCrashC… a.
Which is the currency used in cell respiration?
The currency of energy that is used by cells is called ATP (which pops up often on the AP® Biology exam), which is the product of this reaction. Cell respiration can be broken down into five different steps: glycolysis, formation of acetyl COA, Krebs cycle, oxidative phosphorylation and chemiosmosis.
