Biomolecules
What is the function of carbohyrates?
Provide quick energy for the body
What is the function of ribosomes?
To create proteins
Which types of cells have a cell membrane?
All cells!
Which type of cell transport is specific to describing the movement of water across a semipermeable membrane?
Osmosis
What is an example of something the body would want to keep in homeostasis?
What is the monomer of nucleic acids?
nucleotides
Which organelle directs all of the cells activity?
nucleus
Which organelles are unique to plant cells as compared to animal cells?
Cell walls, chloroplasts, and larger vacuoles
Diffusion, facilitated diffusion, and osmosis all involve substances traveling from high to low concentration. They are examples of __________ transport.
Passive
The A.C. is on really high in the school. Students start to shiver, the movement of their muscles shivering warms them up a little. This is an example of positive or negative feedback?
Negative
What is the monomer of lipids?
glycerol and fatty acids
Which organelle creates glucose using sunlight energy?
Chloroplasts
lysosomes, centrosomes
Which types of cell transport require energy?
Active transport (protein pumps, exocytosis, endocytosis)
If fruit starts to ripen it releases a chemical. If fruits nearby are exposed to that chemical they begin to ripen as well, releasing more of the chemical, continuing the reaction. Is this an example of positive or negative feedback?
Positive
Amino acids make up which biomolecule?
Proteins
Why is mitochondria important in the cell?
To create energy by breaking down glucose
List the differences between prokaryotes and eukaryotes
Prokaryotes always have cell walls, eukaryotes only sometimes.
Prokaryotes do not have membrane bound organelles, while eukaryotes do.
Your salad has started to wilt in the fridge! Your dressing you put on the vegetables was likely (hypotonic/hypertonic/or isotonic) to the plant cells, which caused the wilting to occur.
Hypertonic
A student wants to see what happens if they get their blood pressure out of homeostasis. They decide to do jumping jacks and then take their blood pressure right after using a blood pressure cuff, and then several minutes later to see how the body responds. What are the independant and dependant variables in their test?
IV: activity (exercising)
DV: blood pressure
What happens in hydrolysis?
A disaccharide is split into two monosaccharides as water is added.
Which organelles are involved in protein creation and transport
ribosome, ER, and golgi
List the levels of biological organization in order from least complex to most.
cells, tissues, organs, organ systems, organism
If someone drinks an absurd amount or water, this causes the solution around their cells to be only 5% solute, while their cells have 10% solute. The solution is ________ to the cell, cause water to move _______ the cells.
hypotonic, into
If you chug a couple gatorades, causing your blood sugar to rise and to become hypertonic to your cells. What can your body do to return to homeostasis.
Osmosis--> water will move out of your cells until they reach equillibrium
Also, let sugar out of your blood tream and into your cells to be sent to mitochondria (insulin)
