movement in and out of cell membrane
what type of cellular transport requires energy?
Active transport
what is the primary unit of energy in cells?
ATP
where does photosynthesis occur?
chloroplast
what happens if there is little to no oxygen after glycolysis occurs?
anaerobic respiration takes place
does diffusion require energy?
what simple sugar do most cells rely on as their primary fuel source?
glucose
what are three factors that affect enzyme activity?
temperature, PH level, and substrate concentration
what is the word equation for photosynthesis?
carbon dioxide + water --> glucose + oxygen
(light energy and chlorophyll is required)
what are the products of cellular respiration?
carbon dioxide + water + ATP
what is the definition of equilibrium?
When a solute is spread equally between the inside and outside of the cell membrane.
why are protein pumps needed?
to move substances such as ions and small molecules across the cell membrane against their concentration gradient
leaf/leaves
what are the three cycles involved in aerobic respiration
2. Kreb's Cycle
3. Electron Transport/chemiosmosis
bernaldo drops salt on a leech because he doesn't like leeches and it shrivels up. what type of passive transport is this?
osmosis
what is an allosteric inhibitor?
a molecule that binds to an enzyme (not at the active site) and causes a change in the enzyme's structure and makes the active site unusable.
what is the role of chlorophyll in photosynthesis?
converts light energy into chemical energy
what does fermentation in yeast produce?
alcohol + carbon dioxide
Which of these two molecules require facilitated diffusion to move in and out of the cell membrane?
Glucose or Carbon Dioxide?
Glucose
what happens to a cell if placed in a hypotonic solution?
water moves into the cell, causing the cell to swell up
guard cells can expand to close the stoma. Predict what this would do to gas flow.
gas flow would slow down
where does cellular respiration occur in prokaryotic cells?
