The chromosomes move away from each other to opposite sides of the cell
Back
What do ion pumps do in active transport?
Front
Moves substances from lower to higher concentration (which it doesn't want)
Back
What is homeostasis?
Front
The body maintaining a steady internal temperature.
Back
What happens during exocytosis?
Front
Takes the thing and pushes it out
Back
What is the function of the cytoskeleton?
Front
Keeps the cell's shape
Back
What is the function of the golgi apparatus?
Front
Puts the finishing touches on proteins
Back
What are the steps of the scientific method?
Front
PHEOC
P - Problem
H - Hypothesis
E - Experiment
O - Observation
C - Conclusion
Back
Draw an atom of sodium. Label the correct number of protons, neutrons, and electrons.

Why is photosynthesis vital for life on earth?
Front
1. It creates oxygen which we need to breathe
2. Food supply
3. it produces food for the plant so this cycle can continue to happen
Back
What is the equation for cellular respiration?
Front
C6H12O6 + 6O2 → 6CO2 + 6H2O + ATP
(opposite of photosynthesis)
(glucose + 6 oxygen →6 Carbon dioxide + 6 water + ATP)
Back
What is an enzyme and what roles do they play in the body?
Front
An enzyme is a catalyst in living things. (catalysts speed up chemical reactions and lower activation energy)
Without enzymes the reactions would take place too slowly for us to survive.
Back
What is the function of the nucleus?
Front
The cell's brain
Ribosome assembly begins here
Back
What is the difference between eukaryotic and prokaryotic cells?
Front
Eukaryotic cells are much more large and complex than prokaryotic cells. Eukaryotic cells separate DNA from the rest of the cell and prokaryotic cells don't. eukaryotic cells have a nucleus.
Back
What are the types of active cell transport?
Front
Endocytosis, Exocytosis, and ion pumps.
Back
What do carbs do for the body? Give examples.
Front
Carbs are converted to glucose and made into energy.
Ex. Sugars and starches
Back
What is the function of the vacuole?
Front
Storage area for carbs and lipids
Back
What is the function of ribosomes?
Front
Beginning of protein assembly
Back
What is the function of the mitochondria?
Front
Power house of the cell
Back
What is the function of lysosomes?
Front
Gets rid of toxins within enzymes
Back
What is passive transport?
Front
Cell transport that doesn't require energy
Back
What is the function of cytoplasm?
Front
It is everything in the cell but the nucleus and the membrane
Back
What is the function of chromosomes?
Front
They hold DNA
Back
What happens during prophase?
Front
The chromosomes become visable
Back
What is the function of the cell membrane?
Front
Support of the cell that keeps everything together
Back
Draw the cell cycle and describe what happens during this.
Front
G1 - Growth
S - DNA replicates
G2 - More Growth
M - The cell is actually dividing
Back
What happens during telophase?
Front
Two new nuclear envelopes form and there are now 2 new cells.
Back
What is the organization of cells in a multicellular organism?
Front
Organelles
Individual Cells
Tissues
Organs
Organ System
Back
What is active transport?
Front
Cell transport that requires energy (ATP)
Back
Draw/describe an ATP molecule
Front
ATP molecules have 3 phosphates
Back
What do lipids do for the body? Give examples.
Front
Helps you digest, absorb, and transfer food to energy.
Ex. Fats, oils, cholesterol
Back
What happens during facilitated diffusion?
Front
Molecules can't diffuse across the membrane because they are too charged or too large so they go through special protein channels.
Back
What is the function of the chloroplast?
Front
Photosynthesis happens here
Back
What is the function of the rough/smooth endoplasmic reticulum?
Front
Lipids assemble
Rough ER has ribosomes on it
Back
What happens during diffusion?
Front
The particles move across the membrane until equilibrium is reached. They continue moving but equilibrium is still there.
Back
What do proteins do for the body? Give Examples.
Front
Protein is used to build and repair tissues, make enzymes, hormones, and other body chemicals. Proteins are building blocks of bones and muscles.
Ex. Meats
Back
Where does most of the energy on earth come from?
Front
The sun
Back
How does pH affect the function of an enzyme?
Front
The pH changes the shape of the enzyme and makes it so the substrate can't fit. The substrate and enzyme need to fit perfectly so if the enzyme has changed shape, they won't fit therefore the enzyme activity decreases.
Back
What are the steps of the M phase?
Front
PMAT
P - Prophase
M - Metaphase
A - Anaphase
T - Telophase
Back
What are the eight characteristics of life?
Front
Reproduce, grow and develop, adapt, made of cells, contain genes, eat to survive, respond to stimuli, maintain a constant body temperature, and evolve over time.
Back
How does substrate concentration affect the function of an enzyme?
Front
Enzyme activity increases. The concentration of the substrate increases the rate of reaction because it is more likely that the substrate will find an enzyme to run into.
