What are 3 differences between photosynthesis and cellular respiration?
Cellular respiration takes place in the mitochondria of cells. While photosynthesis requires energy and produces food, cellular respiration breaks down food and releases energy. Plants perform both photosynthesis and respiration, while animals can only perform respiration.
What is the role of glucose in cellular respiration?
The Cellular Respiration Process The metabolism of glucose to yield energy in the form of adenosine triphosphate (ATP) and CO2 (carbon dioxide, a waste product in this equation) is known as cellular respiration.
What role does o2 play in cellular respiration quizlet?
What role does oxygen play in cellular respiration? A. It acts as the final electron acceptor in the electron transport chain.
Why does cellular respiration so important to the organism?
The purpose of cellular respiration is simple: it provides cells with the energy they need to function. If living things could not get the energy they need out of food, it would be absolutely worthless. All living things would eventually die, no matter the quality and amount of food.
Which of the following is the best definition of cellular respiration?
Cellular respiration is the process through which cells convert sugars into energy. To create ATP and other forms of energy to power cellular reactions, cells require fuel and an electron acceptor which drives the chemical process of turning energy into a useable form.
What is respiration explain?
“Respiration is defined as a metabolic process wherein, the living cells of an organism obtains energy (in the form of ATP) by taking in oxygen and liberating carbon dioxide from the oxidation of complex organic substances.”
What is importance of respiration?
Respiration is important because it produces energy that is essential for the normal functioning of the body. Respiration provides cells with oxygen and expels toxic carbon dioxide.

What is the root word of respiration?
The Latin root, respirare, means “breathe again” or “breathe in and out,” from re-, “again,” and spirare, “to breathe.”
What word is used to describe respiration which uses oxygen?
Respiration using oxygen to break down food molecules is called aerobic respiration . Glucose is the molecule normally used for respiration – it is the main respiratory substrate .
