QuestionAnswer
What is Biochemistry?Combination of biology and chemistry. It is the chemistry of life, the domain of large biomolecules.
Definition of work and its equationWork 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.

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 video1. 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 twoProkaryotic 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.

The cell wall of a eubacteria is composed of _____________.Peptidoglycan
Eubacteria reproduce asexually by _______ and _______.Budding and fission
Describe eubacteriaProkaryotes (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 archaebacteriaProkaryotes (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 eukaryotesHave true nucleus and membrane-bound organelles Cell size generally ranges from 10-100 um At least 4 lineages (Protista, plantae, fungi, and animalia)
