Endomembrane Study guides, Class notes & Summaries

AP Biology Exam #3 Endomembrane organelles group of membranes and organelles that work together to modify, package, and transport proteins and lipids Nucleus The central part of the cell containing DNA and RNA and responsible for growth and reproduction - contains the nucleolus, chromatin, and nucleoplasm Contain genetic material The nucleus is enclosed by the nuclear envelope Nuclear envelope Has a double membrane and contains pores that regulate entry and exit of materials ...

The various parts of the endomembrane system serve different functions in the cell. In this activity, you will identify the roles of each part of the endomembrane system. A: Lipid Synthesis B: Calcium Ion Storage C: Poison Detoxication D: Protein Synthesis E: Protein Modification and Sorting F: Cisternal Maturation G: Macromolecule digestion H: Autophagy correct answers Smooth ER: A, B, C Rough ER: D Golgi Apparatus: E, F Lysosomes: G, H All proteins are synthesized by ribosomes in...

Hypothesis - Tentative explanation for an observation, phenomenon, or scientific problem that can be tested by further investigation Variable - To vary or change Independent Variable - A manipulated variable in an experiment or study whose presence or degree determines the change in the dependent variable (thecause) Dependent Variable - The observed variable in an experiment or study whose changes are determined by the presence or degree of one or more independent variables (the effect) C...

Nucleus - Control center of the cell. Contains DNA in the form of genes. Rough Endoplasmic Reticulum - System of internal membranes within the cytoplasm. Membranes are rough due to the presence of ribosomes. functions in transport of substances such as proteins within the cytoplasm Smooth Endoplasmic Reticulum - An endomembrane system where lipids are synthesized, calcium levels are regulated, and toxic substances are broken down. Mitochondria - An organelle found in large numbers in most ...

This is the presumed precursor of the: Kidney 00:57 01:39 In cell Biology what can limit the progress of science? Technology True or False: In you own multicellular body, cells with different ...

Endomembrane system components 1. Nuclear envelope 2. Endo Reticulum 3. Golgi aparatrus 4. Lysosomes 5. Plasma Membrane 6. Vesicles Endoplasmic Reticulum -extends off the nuclear envelope -a network of membrane bound compartments *rough ER and smooth ER* Exocytosis when a vesicles fuses with the plasma membrane *allows the vesicle to empty its contents into the extracellular space OR to deliver proteins embedded in the vesicle membrane to the plasma membrane* Endocytosis when a vesicles buds...
