In a chromatograph of Spinacia oleracea (Spinach) the yellow pigment carotene moves farther than the green pigment chlorophyll. Why does this happen?
Carotene absorbs a shorter wavelength of light than chlorophyll
Carotene is more soluble in the solvent used for the chromatograph than chlorophyll.
Carotene absorbs a longer wavelength of light than chlorophyll
Carotene is less soluble in the solvent used for the chromatograph than chlorophyll.
After a premature birth, the mom of little Timmy asked the doctors for a scan of her newborn to see if there is anything wrong with him. After talking to the doctors, she realized he had one extra chromosome 21. What disease/syndrome did he have and what was the reason?
Jacob Syndrome; extra Y chromosome male
Autistic; tetrasomy 21
Turner Syndrome; monosomy 21
Down Syndrome; Trisomy 21
What makes detergent so good at lowering surface tension
The detergent acts as an enzyme that starts to break down H2O, stopping it form forming hydrogen bonds
The hydrophobic tails avoid water, moving to the surface, disrupting the hydrogen bonds of the water
The water molecules are attracted to the detergent rather than eachother, lessening the number of hydrogen bonds, lowering the surface tension
The detergent acts as that one friend who always breaks apart the strong bonds you and a girl are making
What number would we assign the carbon labeled X on this hexose.
3
1
2
6
Why are many trisomy/monosomy syndromes unnamed?
Controversy surrounding the racist history of genetics.
They are too difficult to identify before the individual’s death.
The syndrome does not occur for certain chromosomes.
Certain chromosomes are too small to properly identify and count.
What substance is transported through the xylem in plants?
Glucose
CO2
Water
Oxygen
What will happen to the Calvin Cycle if the light-dependent reactions stop?
It will slow down since the plant cells will no longer be able to recycle ADP and NADP, causing it to run out of energy.
It will continue as normal, since it does not depend on light
It will speed up, since the plant can use more energy on it, instead of the light-dependent reactions.
It will slow down since the plant cells need light as an energy input to build trioses.
What is most likely to happen to a cells SA/Vol ratio as the cells radius increases
The ratio increases
The ratio decreases
The ratio is unaffected by the diffusion distance
An amino acid is made of . . .
An amino, r, and carboxyl group
A phosphate, r, and methyl group
A carboxyl, hydroxyl, and amino group
A sulfhydryl, methyl, and hydroxyl group
A pleated sheet of proteins is . . .
Primary structure
Secondary structure
Tertiary structure
Quaternary structure
What dictates how tertiary structure is formed?
Interactions between hydrogen atoms
Bonds formed by the Nitrogen-Carbon-Carbon backbone of the amino acids
Interactions between r groups
Bonds between the carboxyl and amino groups
In what order is each element most commonly found in the human body
Carbon, Oxygen, Hydrogen
Nitrogen
Phosphorus
Sulfur
Where does the light dependent reaction happen?
Stroma
Thylakoid Lumen
Granum
Chlorophyll
Where does the light independent reaction happen?
Stroma
Thylakoid Lumen
Granum
Chlorophyll
Which is a type of bond used in the secondary structure of a protein?
Di-sulfide bridges
Covalent bonding
Ionic bonding
Hydrogen bonds
If coenzyme Q (a shuttling protein between protein complexes 1 and 2 of the Electron Transport Chain) does not function, how could this affect water production?
It would cause less water to be produced because electrons are blocked from moving through the ETC.
It would cause a buildup of excess water because there are no electrons for the molecule to bind to.
It would cause less water to be produced because the electrons in the transport chain would be pushed to the intermembrane space.
It would cause more water to be produced because the water molecule would be stable due to a lack of electrons.
What enables the function of the Palisade Mesophyll
The space in between allows for gas like CO2 to reach the chlorophyll more easily
It can grow bigger to allow water an minerals to move through the plant
The high concentration of chlorophylls makes it the primary site of photosynthesis
It's ability to open and close allows for gas to enter and exit the leaf
