Respiration and Cycles Test Review Flashcards
Put the evolution of photosynthesis, aerobic respiration, and glycolysis in order.
Glycolysis (anaerobic respiration), photosynthesis, aerobic respiration
Which has more energy: ADP or ATP?
ATP
How does ADP form?
When ATP loses a phosphate
What is ATP used for?
To use and store energy/to do work
What is ADP used for?
Conversion into ATP and storing/transferring energy to a lesser extent
What are the reactants of glycolysis?
Glucose, 2 ATP
What are the products of glycolysis?
2 ATP, 2 NADH, 2 pyruvate
What are the byproducts of glycolysis?
1 C02
What are the reactants of aerobic respiration?
1 Glucose, O2
What are the products of aerobic respiration?
38 ATP
What are the byproducts of aerobic respiration?
6 CO2, 6 H2O
What are the reactants of lactic acid fermentation?
Glucose
Does anaerobic respiration have glycolysis?
Yes
What are the products of lactic acid fermentation?
NAD+, 2 ATP, and lactic acid
Reactants of alcoholic fermentation
Glucose
Products of alcoholic fermentation
NAD+ and 2 ATP
Byproducts of alcoholic fermentation
CO2 and ethanol
Reactants of photosynthesis
6 CO2, 6 H2O
Products of photosynthesis
Glucose
Byproduct of photosynthesis
O2
Where in anaerobic respiration is ATP made
Glycolysis
Purpose of breaking down pyruvic acid
The NADH is broken down and turned into NAD+ to be reused
NADH function
Delivers e- molecules used during ETS to move H+ ions from low to high concentration (across a membrane)
NADH made
Glycolysis and the Krebs Cycle
FADH2 function
Used during the ETS to move H+ ions from low to high concentration across a membrane
FADH2 made
Krebs Cycle
NADPH function
Carries H+ atoms from the water so they can be used in the Carbon Cycle
NADPH made

Facultative anaerobes are
Bacteria that can function both with and without oxygen
Obligate aerobes are
Bacteria that will die without oxygen – can only function with it
Obligate anaerobes are
Bacteria that will die with oxygen – can only function without it
A facultative anaerobe will only respire anaerobically when
Oxygen is not available
What organisms can photosynthesize
Plants, photosynthetic bacteria, and algae
What organisms respire
All of them – plants and animals
How often do organisms respire
All the time
When do organisms photosynthesize
Only when there is light
What does oxygen do in aerobic respiration
Picks up H+ and electrons to form water
Oxygen is called the
Final electron acceptor
Chemosynthesis is
Uses inorganic energy to make sugars
Photosynthesis is
Uses light energy to make sugars
