_______ is the first step in cellular respiration that begins releasing energy stored in glucose.
The carriers for energy and high energy electrons during GLYCOLYSIS are _____
If oxygen is NOT present, glycolysis is followed by ______
Name the 3 carbon molecules produced when glucose is broken in half during glycolysis.
Since fermentation does not require oxygen it is said to be ______
Which high energy electron carrier is regenerated during fermentation that allows cells to continue to make ATP using glycolysis?
How many ATP molecules are added to get glycolysis started?
Since glycolysis produces 4 ATP molecules, this results in a NET GAIN of _____ ATP's
Write the complete overall chemical equation for cellular respiration using chemical symbols instead of words
Alcoholic fermentation equation in words
Carbon dioxide+Hydrogen→Ethonal+CO2 +2ATP
Lactic acid fermentation in words
Carbon+Oxygen+ Hydrogen→Carbon Dioxide+Lactic Acid+ 2ATP
If alcoholic fermentation is used to make bread dough rise, how come you don't become intoxicated when you eat the bread?
The bread loses the alcoholic content due to evaporation of the alcohol when it is cooked
What is the sequence during cellular respiration
Glycolysis → Krebs cycle → Electron transport chain
Where do the carbon atoms in pyruvic acid end up following the Krebs cycle?
They become part of a carbon dioxide molecule and end up in the atmosphere
Because cellular respiration requires oxygen it is said to be_______
How many total ATP molecules are produced by 1 molecule of glucose completing cellular respiration ?
What is produced during the krebs cycle ?
ATP, NADH, FADH2, CO2
What molecule is the final electron accepter at the end of the Electron transport chain?
The movement of which ion across the membrane from the inter membrane space to the matrix causes ATP synthase to spin and make ATP
Which stage of cellular respiration produces the most ATP?
________is a 6 carbon molecule that is produced when acetyl-CoA joins with a 4 carbon molecule to enter the Krebs cycle.
_________is the process of splitting a glucose molecule into 2 pyruvic acid molecules.
The molecule used by cells to store and transfer energy is
Glycolysis happens outside the mitochondria in the_________of the cell.
___________happens when oxygen is present and includes glycolysis, Krebs cycle, and Electron transport.
This high energy electron carrier produces fewer ATP than NADH as its electrons pass through the Electron Transport Chain because it enters farther down the chain
Inter membrane space
Type of fermentation used by human muscles in low oxygen conditions and microorganisms to make yogurt, cheese, pickles, sauerkraut and kimchi.
As electrons pass down the electron transport chain, H+ ions build up in the
Inter membrane space
The_________cycle breaks down pyruvic acid into carbon dioxide and produces NADH, FADH2, and ATP.
The NADH and FADH2 produced during the Krebs cycle pass their electrons down the_________ chain to produce ATP.
The passage of H+ ions through________causes it to spin and produce ATP.
This 3 carbon molecule is produced during glycolysis when glucose splits in half
Cell organelle which acts as the cell's power plant to burn glucose and store energy as ATP
If oxygen is NOT present, glycolysis is followed by
Type of fermentation used to make bread dough rise and produce beer and wine.
This molecule has the formula C6H12O6 and is split in half during glycolysis
The carbon atoms in pyruvic acid end up as________in the atmosphere following the Krebs cycle.
The folded inner membranes inside a mitochondrion are called_________
This molecule reacts with pyruvic acid to release C02, produce NADH, and acetyl-CoA.
Co enzyme A
________forms when Coenzyme A attaches to two carbons from pyruvic acid.
_________is the storage form of glucose used by animal cells which can be broken down for energy when glucose is used up.
The area inside the cristae where the Krebs cycle happens is the_______
