Cellular Respiration Flashcards
Requires oxygen and occurs in the mitochondria, generates many ATP
Aerobic Respiration
Occurs in the cytoplasm in the absence of oxygen - generated much fewer ATP
Anaerobic Respiration
A series of chemical reactions that break down glucose to produce ATP
Cell respiration
Chemical process by which molecules such as glucose are broken down anaerobically
Fermentation
site of cellular respiration
Mitochondria
Glucose broken down into pyruvate
Glycolysis
pyruvate broken into CO2 and water
Krebs cycle
Cellular energy is aka
ATP
The biochemical reactions that take place within the cell
Metabolism
What happens to Glucose during cell respiration
It gets “burned” and tuned into ATP
What is the “Energy currency” within a cell
ATP
When cells need energy to do work who breaks the high energy ATP bonds
enzymes
Why do enzymes break high energy ATP bonds
to release energy stored in ATP
What is the cell respiration equation (chemical and words)
C6H12O6 (Glucose) + O2 (Oxygen) —> CO2 (Carbon dixiode) + H2O (Water) + ATP (ATP)
Go to slide 6: Wheres the high energy bond?
The red squiggly spaces
What is a term used to describe Photosynthesis and cellular respiration
Complementary
What are the 3 cellular respiration steps
- Glycolysis
- Citric acid (krebs cycle)
- Electron transport chain
Where does glycolysis happen
Cytoplasm
Where does Pyruvate Oxidation happen
Mitochondrial matrix
Where does the krebs cycle happen
Mitochondrial matrix
Where does the Electron transport chain happen
Inner Mitochondrial Membrane
Glycolysis equation
Glucose —> 2 pyruvate + 2 ATP + 2 NADH
Cell respiration without oxygen
Anaerobic
Cell respiration that requires oxygen
Aerobic
Where does Aerobic respiration happen
mitochondria
Where does Anaerobic respiration happen
cytoplasm
How much ATP does anaerobic respiration make
2
how much ATP does Aerobic respiration make
36
During cell respiration if O2 is available, pyruvate is taken into the mitochondria and what steps occur
2-3
Anaerobic respiration- how much ATP is made after Glycolysis
None
What causes the burning feeling in muscles during exercise
Latic acid
What are the two types of anaerobic respiration
Alcoholic fermentation and Lactic acid fermentation
In cells the energy available in food is used to make an energy rich compound called
ATP
The first step in releasing energy of glucose in the cell is known as
glycolysis
Go to slide 7: Whats A
Glycolysis
Go to slide 7: Whats B
Krebs cycle
Go to slide 7: Whats C
Electron transport chain
What process use ATP as a energy carrier (respiration)
Both
The process by which cells make ATP by breaking down organic compounds
cellular respiration
three carbon product of glycolysis
pyruvic acid
Fermentation and cellular respiration are both processes that break down glucose and
release energy from bonds
the space inside the inner membrane of a mitochondria
mitochondrial matrix
Process that produces large amounts of ATP
aerobic
yeast use this process to convert pyruvic acid to ethyl alcohol and carbon dioxide
alcoholic fermentation
When is NAD+ regenerated for the use in gycolysis
latic acid fermentation
What step of cellular respiration is anaerobic
glycolysis
What are the reactants of the electron transport chain
O2, FADH2, NADH
Gycolysis is to pyurvic acid as the krebs cycle is to
ATP
The krebs cycle and electron transport chain are… (What type of respiration)
aerobic
What must pyruvic acid be converted into before the Krebs cycle can proceed?
acetyl CoA
What are the reactants of the Krebs Cycle?
pyruvate, acetyl CoA, NAD+, FAD
What are the products of the Krebs Cycle?
H2O, NADH, 2 ATP, FADH2, CO2
What are the products of the Electron Transport Chain?
ATP(up to 34), H2O, FAD, NAD+
