Levels of Organization
This is the simplest level of biological organization.
What is the chemical level?
A bond where one atom gives up electrons and another gains them.
A sugar with six carbons belongs to this group of saccharides.
What is a hexose sugar?
This gas makes up about 21% of Earth’s atmosphere and is essential for cellular respiration.
What is oxygen?
This theory says an enzyme’s shape allows it to fit specifically with its substrate.
What is the active theory or "lock-and-key" theory?
The smallest unit of an element that still keeps its identity.
What is an atom?
This type of bond helps maintain the shape and proteins of hair.
What is a disulfide bond?
Two simple sugars joined together make this kind of carbohydrate.
What is a disaccharide?
Give the name for the element with the symbol Na.
What is Sodium?
Of the 4 products of respiration — CO₂, water, ATP, and heat — this is a waste gas exhaled by the lungs.
What is carbon dioxide?
The atom is made up of these three subatomic particles with what corresponding charge?
What are protons (+), neutrons (neutral), and electrons (-).
Atoms are usually neutral because the number of these two particles are the same.
What are protons and electrons?
Three fatty acids bonded to one glycerol form this type of lipid.
What is a triglyceride?
Provide the element name for Mg and P.
What are magnesium & phosphorus?
This is the destination of H2O that is a byproduct of cellular respiration.
What is "it becomes part of the INTRAcellular fluid?
Atoms are considered stable when they have this many electrons in their innermost shell, and this many in their outermost shell.
What is the mass of an atom mostly determined by?
What are the protons and neutrons in the nucleus?
Which of these is an example of an unsaturated fat — butter, olive oil, or lard?
What is olive oil?
Match the element to its symbol: Fe, Cu, K.
What is Fe = Iron, Cu = Copper, K = Potassium?
This is the destination of heat that is a byproduct of cellular respiration.
What is "it contributes to normal body temperature"?
Which 3 elements are always found in carbohydrates?
What are carbon, hydrogen, and oxygen?
This type of bond is relatively strong but becomes weaker in water.
What is an ionic bond?
This nucleic acid forms a double helix “twisted ladder” and carries genetic information.
What is DNA?
What is the name for the element with the symbol Mn?
What is Manganese?
In cellular respiration, this molecule stores usable energy for cells.
What is ATP (adenosine triphosphate)?
