| What is Biochemistry? | Combination of biology and chemistry. It is the chemistry of life, the domain of large biomolecules. |
| Definition of work and its equation | Work is the capacity to do work. E= mc^2 |
| What is chemistry? | A study of matter in which we look at the individual atoms and how they interact to each other to form lighter compounds, larger molecules. |
| Cell theory | 1. The cell is the smallest unit of life 2. All organisms are composed of one or more cells 3. New cells arise from previously existing cells |
| What are the 4 components of cell? | 1. Plasma membrane 2. Region containing the dna 3. Cytoplasm 4. Biochemical molecules and biochemical pathways. |
| Enumerate the six different cells mentions in the video | 1. Cells that connect body parts or cover and line organs. e.g. epithelial cells, fibroblast, erythrocytes 2. Cells that move organs and body parts. e.g. skeletal muscle cell and smooth muscle cell 3. Cell that stores nutrients. e.g. fat cell 4. Cell that fights disease. e.g. macrophage 5. Cell that gathers information and controls body functions. e.g. nerve cell 6. Cell for reproduction. e.g. sperm |
| Two types of cell. Differences between the two | Prokaryotic and Eukaryotic cells. Prokaryotic cell has no nucleus, no organelles, and is small that ranges from100 nm - 5 um, on the other hand, eukaryotic cell has a true nucleus, has membrane-bound organelles, ranging from10-100 um, some are larger. |

| Three domain system | Eubacteria, Archaebacteria, Eukarya |
| Eight kingdom system | Eubacteria, Archaebacteria, Archezoa, Chromista, Protista, Plantae, Fungi, Animalia |
| Eubacteria reproduce asexually by _______ and _______. | Budding and fission |
| Describe eubacteria | Prokaryotes (no true nucleus, no membrane-bound organelles) Cell wall is composed of peptidoglycan. Reproduce asexually by budding and fission. Very small (1-10 um) |
| Describe archaebacteria | Prokaryotes (No true nucleus, no membrane-bound organelles like mitochondria or chloropast) No peptidoglycan in cell wall Reproduce asexually by budding and fission Very small (1-10 um) Thrive in extreme environments (high temperatures) |
| Describe eukaryotes | Have true nucleus and membrane-bound organelles Cell size generally ranges from 10-100 um At least 4 lineages (Protista, plantae, fungi, and animalia) |
| Central part of the cell | Nucleus |
| Proteins that are found in plasma membrane | Peripheral protein, integral protein, and glycoprotein |
| Protein that is integrated in the plasma membrane | Integral protein |
