Cellular Respiration Flashcards
Respiration
The breakdown of food molecules (like carbs and fats) to release chemical energy in your body
Molecules that show respiration
C6 H12 O6 + 6O2 ——> 6H20 + 6CO2 + energy (ATP)
Glucose&Oxygen Water&Carbon Dioxide&Energy
Energy in the cell is stored in __________
ATP
Energy is used to maintain ______
Life
The presence of _______ determines how much ______ is produced
O2, Energy
3 Kinds of respiration:
Aerobic, Anaerobic, Respiration from fats and proteins
Aerobic: requires ______ occurs in ___ stages
Oxygen, 3
What is Glycolysis?
Breaking down glucose into pyruvic acid
Glycolysis occurs in the _________ of all cells
Cytoplasm
Glycolysis requires _______
Glucose
Glycolysis produces ____ pyruvic acids, ____ ATP, and ___ NADH
2, 2, 2
What is the Krebs Cycle?
Breaking down carbon bonds to get energy out
Krebs Cycle occurs in the __________
Mitochondria
Krebs Cycle requires __ pyruvic acids (from _________)
2, Glycolysis
Krebs Cycle produces ____CO2, ____NADH, and ___ATP
6, 6, 2
What does the Electron Transport Chain do?
Takes energy from NADH and transfers it to ATP
Electron Transport Chain occurs in the __________
Mitochondria
Electron Transport Chain takes ______ and breaks it down and converts it to _____
NADH, ATP
Electron Transport Chain requires ______, ___, _____ (from Krebs)
ADP, P, NADH
Electron Transport Chain produces ___ and ______
ATP, Water
Anaerobic: without ___________
Oxygen
Three types of anaerobic respiration:
Alcoholic fermentation, lactic acid fermentation, respiration from fats and proteins
Alcoholic fermentation is done by ____ and ______
Yeast, bacteria
Alcoholic fermentation forms _____ from ______
Alcohol, glucose
Alcoholic fermentation requires ______ ______ from glycolysis
Pyruvic acid
Alcoholic fermentation produces _____ _______ and ____
Ethyl alcohol, CO2
Lactic acid fermentation in humans builds up in _____ (soreness & cramps)
Muscles
Lactic acid fermentation has ____ acid that chances to ____ acid
Pyruvic, lactic
Lactic acid fermentation requires ____ acid
Pyruvic
Lactic acid fermentation produces ____ ____ and small amounts of ____
Lactic acid, ATP
Respiration from fats and proteins: fats and proteins can be broken down into _______ that can enter the respiration path
Molecules
Respiration from fats and proteins: ____ produce twice as much ATP as ____ because it has twice as many ____
Fats, glucose, bonds
Respiration from fats and proteins: _____ give about the same amount of energy as _____
Proteins, carbs
Why are proteins not preferred?
They are needed to build other proteins and enzymes in your body
When you break down a bond you get _____
Energy
How many carbons are there in glucose? Pyruvic acid? How many pyruvic acids can be produced from one glucose?
6, 3, 2 Pyruvic acids from one glucose
Why pyruvic acids is formed from glucose do we make bonds or break bonds? What do we get as a result?
Break the glucose bond to create pyruvic acids. We get 2 pyruvic acids
What has to happen to pyruvic acid in order to begin Krebs cycle?
It breaks down chemical bonds
How many carbons does Acetyl CoA have? Do we gain or loose carbon? What is formed as a result? Do we make bonds or break bonds? What do we get as a result?
Acetyl CoA: 2 carbons, we lose one
