Cellualar Respiration Flashcards
Compound formed between glucose and pyruvic acid
Intermediate (G3p
Not involved in glycolysis
Oxygen
Fuel molecule broken down in glycolysis
Glucose
Produced by substrate level phosphorylation
Atp
Invested to energize glucose molecule at start of process
Atp
Reduced as glucose is oxidized
NAD+
Glucose converted to two molecules of this
Pyruvic acid
Assembled to make atp
ADP and P
Splitting of sugar
Glycolysis
Carries hydrogen and electrons from oxidation of glucose
NADH
___ anaerobes can make their ATP by fermentation or aerobic respiration
Facultative
___ is an organism that normally uses aerobic respiration to produce ATP, but it can generate ATP without oxygen via alcoholic fermentation
Yeasts
Fermenters replenish their supply of NAD+ by using NADH to oxidize
Pyruvic acid
When oxygen is scarce human muscle cells can make atp by
Lactic acid fermentation
Fermentation enables cells to make ATP in the absence of
Oxygen
For every molecule of glucose consumed, glycolysis produces two molecules of pyruvic acid, two molecules of ATP and two molecules of
NADH
The waste products of alcoholic fermentation are ____ and carbon dioxide
Ethanol
___ is used to make cheese and yogurt
Lactic acid fermentation
Fermentation generates two ___ molecules for every molecule of glucose consumed
ATP
A cell can use ____to generate a small amount of ATP but it must some how recycle its supply of NAD+
Glycolysis
Like aerobic respiration alcoholic fermentation produces ____ gas as a waste product
CO2
Strict _____require anaerobic conditions and are poisoned by oxygen
Anaerobes
Generates most of the ATP formed by cellular respiration
Electron transport and chemiosmosis
Begins the oxidation of glucose
Glycolysis
Occurs outside the mitochondria
Glycolysis
Produces 4AtP per glucose by substrate level phosphorylation but 2 ATP’s per glucose are used to get it started
Glycolysis
Oxidizes NADH and FADH2 producing NAD+ and FAD
Electron transport and chemiosmosis
Carried out by enzymes in the matrix (fluid) of the mitochondria
Krebs cycle
Here electrons and hydrogen combine with O2 to form H2O
Electron transport and chemiosmosis
Occurs along the inner mitochondrial membrane
Electron transport and chemiosmosis
Generates most of the CO2 produced by cellular respiration
Krebs cycle
FADH2 and NADH deliver hydrogen ions and electrons to this stage
Electron transport and chemiosmosis
ATP synthase make ATP
Electron transport and chemiosmosis
Reduces NAD+ and FAD producing NADH and FADH2
Krebs cycle
