animal's digestive organelles
- Contains at least 50 hydrolytic enzymes
- digestion of materials brought into the cell and of materials/organelles inside
the cell (autphagy)
large family of glycoproteins that mediate Ca2+ dependent cell-cell adhesion
and transmit signals from the ECM to the cytoplasm
portion of the photosystem that consists of chlorophyll molecules that capture
light and funnel their energy to a molecule in the reaction centre
family of integral membrane glycoproteins that recognize and bind to a
particular arrangement of sugars in the oligosaccharides that project from
the surfaces of other cells
Don't know?

condensation (dehydration) reaction... hydrolysis
- Cells are highly complex and organized
- Possess a genetic program
- Can reproduce
- Acquire and use energy
- Carry out chemical reactions
- Engage in mechanical activities
- Respond to stimuli
- Capable of self-regulation
PM, genetic info (DNA), similar mechanisms for transcription/translation,
shared metabolic pathways (glycolysis, TCA), ATP, photosynthesis
mechanisms, protein synthesis, proteasomes, cytoskeletal filaments built of
proteins similar to actin and tubulin
penetrate lipid bilayer, usually across whole membrane (transmembrane)
- Amino acids found: predominantly hydrophobic
- Functions: receptors, channels/transporters, agents that transfer electrons
- Amphipathic
