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.
Is cellular respiration a cycle?
The reactions of cellular respiration can be grouped into three stages
: glycolysis (stage 1), the Krebs cycle, also called the citric acid cycle (stage 2), and electron transport (stage 3).
Why are cellular respiration and photosynthesis like a cycle?
Cellular respiration and photosynthesis are important parts of the carbon cycle. The carbon cycle is the pathways through which carbon is recycled in the biosphere. While
cellular respiration releases carbon dioxide into the environment, photosynthesis pulls carbon dioxide out of the atmosphere
.
What type of cycle is cellular respiration?
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.
How will you describe cellular respiration in your own words?
Cellular respiration is
the process that occurs in the mitochondria of organisms (animals and plants) to break down sugar in the presence of oxygen to release energy in the form of ATP
. This process releases carbon dioxide and water as waste products.
Which describes the process of cellular respiration?
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
.
What are the three stages of cellular respiration briefly describe each stage?
Aerobic (“oxygen-using”) respiration occurs in three stages:
glycolysis, the Krebs cycle, and electron transport
. In glycolysis, glucose is split into two molecules of pyruvate. This results in a net gain of two ATP molecules. Life first evolved in the absence of oxygen, and glycolysis does not require oxygen.
How does cellular respiration contribute to the carbon cycle?
Organic molecules made by photosynthesizers are passed through food chains, and cellular respiration
converts the organic carbon back into carbon dioxide gas
.
How are cellular respiration and photosynthesis similar?
Photosynthesis and cellular respiration are similar because
both reactions contain water, carbon dioxide, glucose, oxygen and energy
. … Cellular respiration takes a glucose molecule and combines it with oxygen; the result is energy in the form of ATP, along with carbon dioxide and water as waste products.
How is cellular respiration different from photosynthesis?
The main difference between photosynthesis and cellular respiration is that
photosynthesis is an anabolic process, where the synthesis of organic compounds occurs, storing energy whereas cellular respiration is a catabolic process, where the stored organic compounds are utilized, producing energy
.
Where does respiration and cellular respiration occur?
While most
aerobic respiration (with oxygen) takes place in the cell's mitochondria, and anaerobic respiration (without oxygen) takes place within the cell's cytoplasm
.
Where do the stages of 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.
Why is respiration called as energy released process?
Respiration is a process by which
food is broken down by release of energy
. It is an exothermic process. It is said to be a catabolic reaction where glucose is broken down to yield energy in the form of ATP.
How does cellular respiration relate to our everyday life?
Cellular respiration is carried out by all living species including humans, plants, animals, birds and insects. It is essential for our daily living, as
this metabolic process helps in producing energy by the breakdown of glucose and is also involved in various body metabolisms
.
How would you describe cellular respiration quizlet?
The process of releasing energy by breaking down glucose in the presence of oxygen
.
How is respiration different from cellular respiration?
Respiration (breathing) is the way your body gets oxygen into the lungs from the air outside. Cellular respiration describes how your cells make ATP – a molecule used to provide energy for chemical reactions.
What role does cellular respiration play in the carbon cycle quizlet?
What role does cellular respiration play in the carbon cycle?
It releases CO2 to the atmosphere during acetyl CoA formation
.
