Hemoglobin Basics
What is the main function of hemoglobin?
Oxygen Transport
This enzyme breaks down starch in saliva?
What is Amylase
The function of myoglobin?
What is Stores Oxygen
The model that describes enzymes fitting substrates exactly
What is the Lock and Key Model
low CO2
high pH,
low 2,3-BPG
What is the R-State
Where is hemoglobin found?
In the Red Blood Cells
The enzyme breaks down proteins in the stomach?
What is a protease
The enzyme that does this is pepsin
The location of myoglobin
Where is in the muscle and heart cells.
Heart cells are called myocytes
To Speed up biochemical reactions
What is to need an enzyme
High 2,3-BPG levels
High carbon dioxide (CO₂)
High Temperature
The element in hemoglobin binds to oxygen?
Ferric or Ferrous?
The enzyme is missing in people who are lactose intolerant?
What is Lactase
the number of polypeptide chains myoglobin have?
What is one
In the lock and key model, this represents the key?
This gas increases in the blood when we exercise, promoting the T-state?
What is CO2
How many polypeptide chains does hemoglobin have?
Four (2 alpha, 2 beta)
The enzyme helps copy DNA before cell division?
what is DNA polymerase
This animal has high myoglobin levels for deep diving?
What is a whale
In the lock and key model, this represents the lock?
What is the enzyme
The type of bond is broken when hemoglobin shifts from T-state to R-state?
What are Salt bridges
What happens to hemoglobin when oxygen binds to it?
It changes shape to carry more oxygen (cooperative binding)
The enzyme breaks down fats?
What is lipase
this is the reason why myoglobin bind oxygen more tightly than hemoglobin
What is oxygen storage for muscle use
The place the substrate binds into
What is the active site
The name of the effect where low pH promotes oxygen release?
