1. Cells have selectively permeable membranes that regulate what goes into and
out of the cell
2. Diffusion occurs when molecules move away from areas where there are more
of them into areas where there are fewer/less of them.
3. The diffusion of water through a cell membrane is osmosis.
4. Active transport requires energy to move a substance through a cell
membrane.
5. The process in which the membrane of the vesicle fuses (connects) with the
cell’s membrane and the vesicle’s contents are released from the cell is
exocytosis.
6. Photosynthesis is the process that plants and other organisms (algae and some
bacteria) use to convert light energy into chemical energy or sugars to be used
as food.
7. Organisms that can’t make their own food are consumers/heterotrophs.
8. 2 products of photosynthesis are oxygen and glucose (sugar).
9. Cellular Respiration uses glucose and oxygen and produces carbon dioxide
and water as wastes.
10. Fermentation produces lactic acid, alcohol, carbon dioxide.
11. Respiration occurs in the mitochondria.
12. The movement of substances through a cell membrane without the input/use of
energy is passive transport.
13. Equilibrium occurs when molecules of one substance are spread evenly
throughout another substance, or inside and outside of a cell.
14. Transport proteins move substances into and out of the cell in the process of
facilitated diffusion.
15. The process in which a substance is taken into a cell by surrounding it with the
cell membrane, forming a sphere called a vesicle is endocytosis.
16. Metabolism is the total of all chemical reactions in an organism.
17. Organisms that make their own food are producers/autotrophs.
18. Chlorophyll and other pigments are used in photosynthesis to capture light.
19. The process in which chemical reactions (rxns) break down food molecules into
simpler substances and release stored energy is (cellular) respiration.
20. Fermentation occurs when cells do not have enough oxygen for respiration to
release some of the stored energy in glucose molecules
21. Photosynthesis occurs in the chloroplast
22. Fermentation occurs in the cytoplasm
