Cellular Respirstion Flashcards
Define cellular respiration
So respiration is the process that releases energy from food in the presence of oxygen
Where organisms get the energy they need for life processes
Food
What are the three stages of cellular respiration and when so that each stage occur
Glycolysis- cytoplasm
Kreb cycle- matrix
Etc- inner membrane space
Write the equation for cellular respiration in words and symbols
Words- oxygen+glucose➡️energy+ carbon+ water
Symbols- 602+ C6H12o2➡️energy+ 7CO2 +6 H2O
Describe what happens during glycolysis
During glycolysis sugars are broken down and made into energy. One molecule of glucose ,six carbon compound, is converted into two molecules of pyruvic acid , a three carbon compound
How many ATPs are used to jumpstart glycolysis
2 molecules
What is the net energy gain during glycolysis
2 ATP molecules
Where the products of glycolysis go
To the KREB cycle
What happens during the Krebs cycle
During the Krebs cycle Pyruvic acid is broken down into carbon dioxide in a series of energy extracting reactions
Into what to products is Pyruvate broken down into in the Krebs cycle
Carbon dioxide and acetic acid
How does the cell use the charge differences that build up across the Inner mitochondrial membrane during cellular respiration
The difference causes the ATP synthase to spend as it rotates it grabs ADP molecules and attracts a phosphate group making ATP
What is fermentation
Fermentation is the process of anaerobic respiration and glycolysis. two types are alcoholic fermentation and lactic acid fermentation
Which fermentation is carried out in your body
Lactic Acid fermentation
What are three main sources of ATP available for human muscle cells
ATP already in the muscle ,ATP made by lactic acid fermentation, and ATP made cellular respiration
