Basis of life
| 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 |
