Question | Answer |
________ were the first forms of life | heterotrophs |
why autotrophs were developed | heterotrophs needed nutrients at a faster rate |
____ coined the term cell from a cork | Robert hooke |
_______ discredited spontaneous generation (living come from non living) | Louis Pasteur |
____ fluid mosaic (phospholip bilayer w/t protein | cell membrane |
cell membrane is permeable to | nonpolar, small polar like water. |
charged particles cross the membrane through | protein channels |
____ controls activity of cell | nucleus |
______ where rRNA synthesis occurs | nucleolus |
______ site of protein production | ribosome |
_______ synthesize steroids, lipids and membrane of cell | enoplasmic reticulum |
modifies content from ER and distribute to cell surface | Golgi apparatus |
site of respiration, powerhouse | mitochondria |
transport and store materials; more likely in plants than animals | vacuole |
_____ used during cell division and are lacked by plants | centrioles |
_____ maintains cell shape and contains microtubules | cytoskeleton |
_______ moves down gradient requires a carrier with no energy required | facilitated diff |
______ moves against grad requires energy and a carrier | active transport |
role of enzymes to speed up rxn | lowers activation energy w/o being changed |
do enzymes affect the overall G (gibbs) of a rxn | no |
Induce fit theory | active site is flexible and conforms to fit the substrate |
whats respiration | convert chemical energy to useable energy |
final step of resp is ____ that release energy to form _____ | H acceptor ; ATP |
gluc catabolism occurs stages | glycolysis, cell respiration |
glycolysis results and occurs in | 2 pyruvate; 2atp , 2 nadh, cytoplasm |
pyruvate under fermentation conditions | reduce pyruvate to ethanol / lacttic acid. nad regenerated and produces on 2 atp |
pyruvate under oxygenated conditions/ celll resp | 36-38 atp, occurs in mitochondria |
cell resp divided into 3 stages | pyruv decarb, citric acid cycle/ kreb cycle, electron transport chain |
pyruva decarb occcurs in | mitoch matrix |
results of pyruv decarb | lose CO2 and reduce NAd tonadh |
results of kreb cycle | 2 C acetyl fuses with oxalocetate and releases 2CO2, (3Nadh, 1Fadh,1Atp)*2 |
ETC occur in the | inner mitochon membrane |
results of ETC | Oxygen pix up H forms water and energy used to make ATP |
substrate level phospho produces _____ atp | 4 |
carbs are stored as _____ in the ____ | glycogen; liver |
fats stored in ________ as _____ | adipose tissue; triglyceride |
glycerol can be converted to ______ which can enter the Citric Acid cycle | PGAL |
Calvin cycle | (light independent ) in photosynthesis CO2 is fixed to ribulose bisphosphate |
calvin cycle occurs in | stroma of chloroplast |
wats the prime end product of photosynthesis | PGAL |
where is the light dependent stage of photosynthesis occur | thylakoids |
oxidative phosphorylation produce ___ atp | 32 |
citric acid cycle + glycolysis produce _____ atp | 4 |
stamen | male organ on plant that produces monoploid spores that form into pollen grains |
stigma | female organ site of pollen grain deposition |
style | tube connects the stigma to ovay |
petal | protects female organs and attracts insects |
spores in plants | haploid |
