Cellular Respiration Flashcards
During glycolysis, 6-carbon glucose is broken into?
2 molecules of 3-carbon pyruvic acid or pyruvate
Glycolysis produces a net gain of …?
2 ATP
When oxygen is present, pyruvate enters the Krebs cycle. Where in the eukaryotic cell does this occur?
mitochondria
Oxidative phosphorylation is also known as…..
electron transport chain
This process uses NADH and FADH2 to produce ATP…..
oxidative phosphorylation
Which of the following processes produces the most ATP?
fermentation
Which of the following is necessary for oxidative phosporylation to occur?
Oxygen
Which of the following is the products of the Krebs cycle?
ATP
NADH
FADH
All of these
What are the 2 types of fermentation?
Lactate fermentation and ethanol fermentatio
What does Anarobic mean?
Without oxygen
What are the 3 stages of cellular respiration
Glycolysis
Kerb Cycle
Oxidative Phosphorylation
What is Oxidation?
Loss of electrons
What is reduction?
Gaining of electrons
What does aerobic mean?
Requires oxygen
Is Glycolysis part of the Kreb Cycle? True or False
False
Read the quote and define the term “ metabolic pathway that includes glycolysis and one or two reactions in which NADH is oxidized to NAD+ by reducing pyruvate to other compounds.”
This is known as fermentation
Where does Glycolsis occur
In the cytoplasm
The citric cycle or the tricarboxylic acid cycle is also known as….
The kreb cycle
What is chemical compound for glucose?
C6 H12 O6
During oxidation reactions what is formed by the energy released?
ATP energy
Under anaerobic conditions pyruvate undergoes a process called?
Fermentation
Kreb’s Cycle - begins with a 4C molecule combining with a 2C molecule called __?
acetyl COA
What is the total net gain of ATP at the end of aerobic respiration?
38 ATP
Which type of fermentation occurs in muscles?
lactic acid
What are the SPECIFIC OUTPUTS of Glycolysis?
2 Pyruvic Acid, 4 ATP, 2 NADH
.What is the final electron acceptor in the electron transport chain?
Oxygen (it accepts the e- from the membrane bound electron carriers and it accepts the H+ ions from ATP synthase)
How many ATP’s are made using the electron transport?
32
What is carrying the electrons for the electron transport chain?
NADH and FADH2
How many Co2 are made in the kreb Cycle?
8
What is the protein that makes ATP?
ATP synthase
What is the correct order of cellular respiration?
Glycolysis, kreb cycle, Electron transport chain
What is the net gain of ATP for cellular respiration?
36
What 3 stages of celluar respiration is associated with sugar splitting?
Glycolysis
The kerb cycle involves a series of reactions following a circular path, with each step catalyzed by a different enzyme. True or False
True
Involes redox reactions carried out by molecules in the inner mitochondrial membrane; collectively referred to as the electron transport chain. What am I?
Oxidative Phosphorylation
What process allows glycolysis to continue recycling NAD+?
Fermentation
