Cellular Respiration
The only process of ATP production in cells using fermentation is
glycolysis
The hierarchy of life extends past individual organisms. What is the correct sequence, from least inclusive to most inclusive, following an individual organism?
population-community-ecosystem-biosphere
Dilation of blood vessels in extremities can help animals lose excess heat as part of the thermoregulation. True or False?
True
A diuretic is a substance that...
increases the volume of urine
The three main biochemical pathways of cellular respiration are...
glycolysis, Krebs cycle and electron transport chain
Electrons that reach the end of the electron transport chain are transferred to
Oxygen, thereby reducing it to form water
Which of these is not a required characteristic of life?
Homeostasis, Movement, Structural Organization, Evolution, Energy Use
Movement
Saltwater fish lose water through osmosis. True or false?
True
What are the functional "units" of the kidney?
Nephrons
Which of the following is not true about a hypothesis?
- It can be proven to be true
- It can be rejected
- It is a tentative explanation
- Previous knowledge can help support it
- It must be testable to be useful
It is a tentative explanation
The Krebs cycle runs how many times and why?
Twice, once for each acetyl CoA that was formed from the glucose molecule
A structure, such as a flower in plants, or a liver in animals, consisting of tissues organized to carry out a specific function is a(n)...
organ
Homeostasis means...
the ability to maintain internal stability in an organism in response to the environmental changes
What is the glomerulus?
A cluster of nerve endings, spores or small blood vessels, especially a cluster of capillaries around the end of a kidney tubule: the site of filtration in kidney nephrons
The products of cellular respiration are...
Carbon dioxide, water and ATP
In glycolysis the net number of NADH produced is
2
Thinking about the processes of photosynthesis and cellular respiration in plants, plants are net
- glucose consumers and CO2 producers
- O2 producers and CO2 consumers
- O2 and CO2 producers
- O2 and CO2 consumers
- glucose and O2 consumers
O2 producers and CO2 consumers
A mammal is ___ and has a body temperature ___.
- ectothermic; that changes with fluctuation in environmental temperature
- endothermic; maintained by its own metabolism
- endothermic; that changes with fluctuations in environmental temperature
- ectothermic; maintained by its own metabolism
endothermic; maintained by its own metabolism
Where is filtrate from the glomerulus collected?
In the Bowmans capsule
Cyanide and carbon monoxide block the final step in the electron transport chain. Consequently, ATP production in the mitochondria would...
decrease, because electrons would not be able to move through the electron transport chain
The reactants for cellular respiration are...
glucose and oxygen
Compared to the air a person inhales, the air that they exhale has
- a higher concentration of O2 and a lower concentration of CO2
- a lower concentration of O2 and a higher concentration of CO2
- higher concentrations of both O2 and CO2
- lower concentrations of both O2 and CO2
- equal amounts of O2 and CO2
a lower concentration of O2 and a higher concentration of CO2
