Document Summary
Cell structures and functions: eukaryotic prokaryotic, tissues. Connective tissue: organ systems combine together to form the organism, mitosis / meiosis cell division. Organelles and structures: cell membrane / plasma membrane. Outside hydrophilic (cid:498)water loving(cid:499: protein channels (allow for communication) Passive channel - allow movement across a gradient, high to low (outside of the cell to the inside of the cell) concentration. membrane ribosomes are assembled. Active channels requires energy to move ions across the. Ribosomes will be free and allows for translation of proteins. Rough endoplasmic reticulum allows for the modification: nucleus has a concentrated region called the nucleolus where. Resevoir of calcium which si vital for muscle contrction . Adds lipids or carbohydrates to the protein: golgi apparatus / body sarcoplasmic reticulum or released from thecell. Determines its destination whether the protein will stay in the cell: lysosomes. Break down and recycle proteins so lipids and carbohydrates can reuse it.
