DNA and RNA
what is dna made up of?
DNA is a long molecule made up of units called nucleotides
What is energy?
Energy is the ability to do work
The cell that has a cell wall
What is a plant cell
What are the phases of the cell cycle? *In order*
G1 phase, S phase, G2 phase and then mitosis
What are the two main types of chemical bonds?
covalent and ionic bonds
Are DNA molecules long?
Yes
What would happen if your cells stopped using energy?
They would stop working and you would die.
Two main types of cells
What is Prokaryote and Eukaryote
What are the phases of mitosis?
prophase, metaphase, anaphase, telophase
What are the three subatomic particles that make up atoms?
protons neutrons electrons
Where are DNA molecules located?
Nucleus
Where do we get our energy from?
We get it from food
The diffusion of water through a selectively membrane
What is osmosis
what happens during the S phase?
the cell’s DNA replicates
Why are water molecules polar?
because their is an uneven distribution of electrons between the oxygen and hydrogen
What helps separate chromosomes during mitosis?
Spindle fibers
What is one principal compound that cells use to power proteins?
adenosine triphosphate (ATP)
Name a molecule that cannot diffuse through the cell membrane
What is glucose (or other molecule that cannot pass through)
Are mitosis cells haploid or diploid?
Diploid
what are the functions or or each organic compound
Proteins: speed up chemical reactions throughout the body and perform many cellular options
Carbohydrates: structure and energy storage
Lipids: energy, cell membranes, cell messengers
Nucleic acids: DNA and RNA tell the cell how when and where to make a protein and help make proteins
If the base on the old strand is adenine, thymine is added to the newly forming strand, likewise what would always be paired?
guanine is always paired to cytosine
How are atp and glucose similar and how are they different?
They are both chemical sources of energy used by the cell. However ATP can be used by proteins while glucose energy must be changed to ATP energy by cellular respiration
This organelle detoxify poisons for the cell
What is Smooth ER
Why can cancer be considered a disease of the cell cycle?
The growth of the cell becomes corrupted and they aren’t able to grow and develop into tumors
Describe the structure of an atom?
nucleus that contains protons and electrons with electrons moving around the nucleus
