- endomembrane system
- Golgi apparatus
- a aerobic rod-shaped spore-producing bacterium
- b in eukaryotic cells, the cell organelle that is surrounded by two membranes and that is the site of cellular respiration, which produces ATP
- c stack of membranes in the cell that modifies, sorts, and packages proteins from the endoplasmic reticulum
- d A sticky layer that surrounds the cell walls of some bacteria, protecting the cell surface and sometimes helping to glue the cell to surfaces.
- e The collection of membranes inside and around a eukaryotic cell, related either through direct physical contact or by the transfer of membranous vesicles; includes the smooth and rough endoplasmic reticulum, the Golgi apparatus, lysosomes, and vacuoles.
5 Multiple choice questions
- A network of membranes inside eukarytoic cells invovled in lipid synthesis (steroid in gonads), detoxification (in liver cells), and/or Ca2+ storage (muscle cells); lacks ribosomes on the surface
- double membrane perforated with pores that control the flow of materials in and out of the nucleus
- enzyme-filled vesicle in which fatty acids and amino acids are metabolized to hydrogen peroxide that is broken down to harmless products
- any spherical or nearly spherical bacteria
- Photosynthetic, oxygen-producing bacteria (formerly known as blue-green algae).
5 True/False questions
mesosome → membrane-bound sac containing digestive enzymes that can break down proteins, nucleic acids, and polysaccharides
cell envelope → idea that all living things are composed of cells, cells are the basic units of structure and function in living things, and new cells are produced from existing cells
centrosome → region of cytoplasmic material that in animal cells contains structures called centrioles
granum → A stacked portion of the thylakoid membrane in the chloroplast; functions in the light reactions of photosynthesis.
secretion → Region in prokaryotic cell where DNA is concentrated, not enclosed by membrane
