What is cellular respiration in your own words?
Cellular respiration is a process that occurs in the mitochondria of all organisms. In this process, both plants and animals break down simple sugars into carbon dioxide and water and release energy in the form of adenosine triphosphate (ATP).
What is a cellular respiration easy definition?
: any of various energy-yielding oxidative reactions in living matter that typically involve transfer of oxygen and production of carbon dioxide and water as end products Cellular respiration is a series of reactions, occurring under aerobic conditions, during which large amounts of ATP are produced.—
What is cellular respiration and why is it important?
The main function of cellular respiration is to synthesize biochemical energy. Cellular respiration is essential to both eukaryotic and prokaryotic cells because this biochemical energy is produced to fuel many metabolic processes, such as biosynthesis, locomotion, and transportation of molecules across membranes.
Why is cellular respiration important short answer?
The purpose of cellular respiration is simple: it provides cells with the energy they need to function. Key point: Cellular respiration involves catabolic reaction in order to break down food into usable energy so that cells, and the living organisms that contain them, can survive and thrive.
Why do we need cellular respiration?
All organisms need energy to live. This energy is used: to drive the chemical reactions needed to keep organisms alive – the reactions to build complex carbohydrates , proteins and lipids from the products of photosynthesis in plants, and the products of digestion in animals, require energy.
How does cellular respiration work?
Cellular respiration, the process by which organisms combine oxygen with foodstuff molecules, diverting the chemical energy in these substances into life-sustaining activities and discarding, as waste products, carbon dioxide and water. …
Which is the best definition of cellular respiration?
Define the following terms: a. Cellular respiration (aerobic respiration) (2 points) – the process of oxidizing food molecules to carbon dioxide and water. Glucose is an example. b. Fermentation (anaerobic respiration) (2 points)- metabolic process that converts sugar to acids, gas, or alcohol. 2.
What happens to carbon dioxide during cellular respiration?
Plants on the other hand absorb carbon dioxide, and through both its process of photosynthesis converting light into energy chemically and during the process of cellular respiration, “waste” oxygen which is then recycled by other plants and humans to begin the process anew.
How is photosynthesis a reverse of cellular respiration?
Almost a reverse of what cellular respiration exhibits; photosynthesis combines carbon dioxide molecules and water obtained from its roots, and captures light energy to start the chemical process in which it creates energy and its byproducts.
How is ATP created in the cellular respiration process?
A small amount of ATP is also created during the first two stages as well. ATP is the key to this entire process, as certain amounts of it are created in every step, and simultaneous also spent in each step as well. This creates a self-sustaining cellular cycle of energy production and use.
