Nucleotide known as "molecular currency" as it stores and transports energy.
What reactant does aerobic respiration need that anaerobic respiration does not need?
Which steps of cellular respiration do not happen when oxygen is not present?
Krebs Cycle & ETC
What are the products of glycolysis? (there are 3 products)
2 net ATP, 2 pyruvate, 2 NADH
Which coenzyme cleaves off a carbon from pyruvate during the Krebs Cycle prep step to create acetyl CoA?
Coenzyme A (CoA)
A substance that enhances the action of an enzyme and helps it work
Coenzyme
What is the difference in ATP produced in anaerobic respiration vs aerobic respiration?
Anaerobic respiration --> 2 ATP
Aerobic respiration --> 38 ATP
Which step of cellular respiration produces the most ATP?
ETC
What is produced in the Krebs cycle when carbon is cleaved off of the 6 and 5 carbon molecules?
Carbon dioxide is produced
Which enzyme is situated across the mitochondrial matrix membrane and assists with the creation of ATP as Hydrogen is pumped back across the membrane?
ATP synthase
Three carbon molecule produced when glucose is broken down during cellular respiration
Pyruvate
What is the product of the fermentation pathway that is created in animal cells and causes muscles to burn during prolonged exercise?
Lactate (lactic acid)
Which step of cellular respiration produces 2 ATP, 8 NADH, 2 FADH, and 6 CO2?
Krebs cycle
What is the product of the prep step between glycolysis and the krebs cycle?
Acetyl CoA
This is the general term for when particles or solutes move across a membrane from an area of higher concentration to an area of lower concentration?
Concentration gradient
The anaerobic conversion of sugar to carbon dioxide and alcohol or lactate
Fermentation (Anaerobic respiration)
What is the product of fermentation that occurs in non-animal cells that creates carbon dioxide and often causes a sour smell?
Ethanol
What happens to NADH and FADH during the ETC?
They are oxidized, meaning they lose Hydrogen and electrons
What is the name of the 2 phosphorylated 3 carbon molecules produced when glucose is broken in half during glycolysis?
PGAL
What is the chemical equation for aerobic respiration?
C6H12O6 + 6 O2 --> 6 CO2 + 6 H2O
4 Carbon Molecule that exists in the Krebs cycle; binds with acetyl CoA to make citric acid during the Krebs Cycle
Oxaloacetate
What is the purpose of the biproduct of the fermentation pathway?
To produce recycled NAD+ to reuse during glycolysis as NADH (to regenerate NAD+)
Where do each of the 3 steps of cellular respiration take place?
Glycolysis: cytoplasm
Krebs: mitochondrial matrix
ETC: mitochondrial membrane
What are the final products of the ETC? (3 products)
Water
NAD and FAD
34 ATP
NADH and FADH: carry electrons and hydrogen through the whole process into the ETC
CoA: strips a carbon atom from pyruvate at the start of the Krebs cycle prep step
