A cell has the following molecules and structures: enzymes, DNA, ribosomes, plasma membrane, and mitochondria. It could be a cell from
A bacterium
An animal, but not a plant
A plant, but not an animal
A plant or an animal
Which of the following would be the correct cellular pathway from DNA to the cell secreting a protein?
DNA > mitochondria > lysosomes > cell membrane
DNA > vacuole > ribosomes > cell membrane
DNA > Smooth ER > lyosomses > cell membrane
DNA > Rough ER > Golgi Bodies > cell membrane
The ability of phospholipids to form membranes
Depends on their secondary nature
Depends on their amino acids
Because they are awesome sauce
Is related to their polar and nonpolar properties
Which of the following is NOT true of a hypotonic environment?
Fresh water
Plant and animal cells will both burst
The net movement of water is entering the cell
The outside environment contains less solute than the internal cellular environment
A membrane protein with hydrophobic regions
Would be more fluid than those lacking hydrophobic regions
Would likely be able to span the membrane as an integral protein
Would be a peripheral protein
Would be highly soluble in water
Integral protein channels in the plasma membrane are required for
Simple diffusion only
Osmosis only
Facilitated diffusion only
Facilitated diffusion and active transport
What is the importance of a secondary messenger such as cAMP in the signal transduction pathway?
To torture AP Bio students
To amplify the signal by relaying the message to multiple molecules
To inhibit the signal if there is an excess of chemical signals
To prevent an over-stimulation in the the synaptic gap
Steroid hormones
Bind to cell membrane receptors
Enter cells and bind to cytoplasmic receptors
Rely on secondary messengers to produce their effects
Are derived from proteins
The most vulnerable part of the neuron and it's signal transmission is the
Cell body
Dendrites
Axon
Synaptic gap
Which of the following would describe a positive feedback model?
The response increases the stimulus
It is a corrective measure
The response decreases the stimulus
The response will return the body to normal conditions
