Cellular Respiration
Where in the cell does cellular respiration occur?
The mitochondria
Where do plants get the energy to do photosynthesis from?
the sun
What are the 4 different types of cell signaling?
Autocrine, Gap Junctions, Paracrine, Endocrine
What is the order of the phases of mitosis?
PPMAT
What is the order of the phases of meiosis?
PMATPMAT
Where does glycolysis occur?
What color light do plants not absorb well?
green
What is Apoptosis and what kind of cell signaling causes it?
cell suicide, autocrine
What phase do the chromosomes line up in the middle of the cell?
Metaphase
Meiosis results in ___ genetically __________ daughter cells
4, different
What parts of cellular respiration can happen in anaerobic conditions?
Glycolysis
What is the main product produced by the Calvin cycle and light cycle
sugars, atp
What is signal transduction?
A signal being passed between molecules
Mitosis results in ___ genetically __________ daughter cells
2, identical
In what phase can nondisjunction occur?
Anaphase I or II
What does the electron transport chain use the electron energy for?
pumping protons against the gradient
What is the purpose of having accessory pigments in the chloroplasts for plants?
so they can absorb light in all conditions, also acts as a natural sunscreen
If a signal is released into the bloodstream, will every cell it comes in contact react to the signal? Why?
No, cells all have specific receptors for specific signals
What phase has sister chromatids splitting to opposite sides of the cell?
Anaphase
What non-fatal genetic disorder is caused by nondidjunction?
Down Syndrome
What is the purpose of the proton gradient caused by the electron transport chain?
To have the protons flow through ATP synthase
Which of the following represents the correct flow of electrons during photosynthesis?
H2O -> NADPH -> Calvin cycle
What are the roles of a kinase enzyme and a phosphatase enzyme?
Kinase - Adds phosphate group
Phosphatase - Takes away phosphate group
What is the difference between a centriole, centrosome, and centromere?
centriole - tube (looks like a noodle)
centrosome - structure made of centrioles that create the aster
centromere - Center of chromosome, holds together sister chromatids
Whats the difference between anaphase I and anaphase II?
Homologous chromosomes split in AI and sister chromatids split in AII.
