Document Summary
Neutrophil chase: video 16. 1: a neutrophil is a white blood cell, occurs near red blood cells, signaling allows it to detect bacteria, cell movement occurs via the cytoskeleton and motor proteins, phagocytosis and vesicles digest the bacteria. Calcium signaling: video 15. 4: calcium and neurons, calcium is released which allows the cells to light up, ion channels are important in neuron firing action potentials. Breast cancer cells: video 20. 1: cancer cells are disorganized, cell-cell communication forms tissue, cell division is disregulated in cancer cells, cells get attached to the extracellular matrix and can break off to different parts of the body. Has a cell wall and cell membrane. Have a nuclear membrane and internal organelles with membranes. Yeast is a type of fungi: replicates through budding. Mammalian pancreas cell is specialized for making certain proteins which are packaged into vesicles. Plants have organelles called chloroplasts: have large vacuole with ions and small molecules.
