Question

cellular respiration model analysis
aerobic vs. anaerobic respiration - model 5

1. use models 4 and 5 to fill in the chart below comparing anaerobic and aerobic respiration.

what type of organisms participate in this type of respiration? (who)
what is the starting reaction for this process?
what is the starting reactant for this reaction? (what)
what is the end product of this type of reaction? (what)
how much atp is made during this reaction? (what)
does this happen with or without oxygen being present? (when)
in what cellular location does this type of respiration take place? (where)
why do cells undergo this type of reaction? (why)

1. which type of respiration, aerobic or anaerobic results in the production of more atp?

Explanation:

Anaerobic respiration occurs in organisms like bacteria and yeast in the absence of oxygen, starting with glycolysis (glucose as reactant), producing lactic - acid or alcohol and carbon - dioxide, and generating 2 ATP in the cytoplasm, mainly to produce energy quickly when oxygen is scarce. Aerobic respiration occurs in most eukaryotic organisms in the presence of oxygen, also starting with glycolysis (glucose as initial reactant), but then proceeding through the Krebs cycle and electron transport chain in mitochondria, producing carbon - dioxide, water and about 32 - 38 ATP, to efficiently generate a large amount of energy for cellular functions.

Answer:

	Anaerobic	Aerobic
What is the starting REACTION for this process?	Glycolysis	Glycolysis
What is the starting reactant for this reaction? (WHAT)	Glucose	Glucose
What is the end product of this type of reaction? (WHAT)	Lactic acid or alcohol and carbon - dioxide	Carbon - dioxide and water
How much ATP is made during this reaction? (WHAT)	2 ATP	32 - 38 ATP
Does this happen with or without oxygen being present? (WHEN)	Without oxygen	With oxygen
In what cellular location does this type of respiration take place? (WHERE)	Cytoplasm	Mitochondria
Why do cells undergo this type of reaction? (WHY)	To produce energy quickly when oxygen is scarce	To efficiently generate a large amount of energy for cellular functions

1. Aerobic respiration results in the production of more ATP.
