Cells Stuff Flashcards
Cytoplasm= (components)
cytosol (water soluble fluid) and organelles
Name the Organelles ~7
- Mitochondria
- Ribosome
- Lysosome
- Rough ER
- Smooth ER
- Nucleus
- Golgi Apparatus
Ribosome fn
protein synthesis
Lysosome fn
membrane-bound, breakdown of molecules though enzymes
Rough ER
plays a role in the synthesis and export of proteins, associated with ribosomes
Smooth ER
involved in the synthesis of lipids
Nucleus
holds chromosomal info
Golgi apparatus
transports, modifies and packages proteins and lipids, also membrane bound
Cytoskeleton contains…
microfilaments, intermediate filaments, thick filaments and microtubules extending through the cytoplasm in cells
Microvilli
increase surface are in order for better absorption. uptake and secretion of molecules
cilia
hair-like filaments that facilitate movement, especially of fluid, by a vibrating motion
Diffusion
concentration high -> low
osmosis
movement of solvents across and semi-permeable membrane
Active transport
movement from low concentration -> hight concentration
Endocytosis
uptake to molecules by merging with cell membrane
Exocytosis
vacuoles filled with molecules merge with cell membrane to expel things
Phagocytosis
uptake and digestion of bacteria and other molecules by phagocytes. they ingest them basically. ie: macrophages (white blood cells)
Phases of mitosis
Prophase, Metaphase, Anaphase and Telophase
Meosis=
gamete production through cell division
4 main biomolecules
Carbohydrates
Lipids
Proteins
Nucleic Acids
Cellular respiration is
for the production of ATP Energy!! involves glucose, oxygen, carbon dioxide and water
ATP can be used for…
muscle contraction, ion flow
fatty acids are
lipids+ glycerol
Proteins level
primary, secondary, tertiary, quaternary. are everywhere in the body and help build muscle
Ex of nucleic acids
DNA, RNA
Cellular respiration meaning,
production of ATP
oxidative respiration:
O2 + Gluc -> ATP + H2O+CO2
Aerobic vs anaerobic respiration
aerobic- producing ATP using O2
Anaerobic- w/out O2
Water fn in body
60-80% of body weight,
big help im maintaining body temp, conducts heat (for insulating or keeping from overheating.
