unit 1 quiz

Proteins used for enzymes enzymes speeds up chemical reactions by lowering the activation energy needed mitochondria converts glucose to ATP rough endoplasmic reticulum stores and moves proteins made on the ribosomes lysosomes digest worn out organelles Lipids source of energy and insulation Which structure does NOT belong in a prokaryotic cell? nuclear membrane ribosomes phospholipid membrane cytoplasm How are chloroplasts similar to mitochondria? They are both found in prokaryotic cells They are both found in animal cells They both contain their own DNA The both can use energy from sunlight How does the cell membrane in the drawing above help to maintain the health of this cell? by providing support and structure for the cel by storing food as future energy for the cell by manufacturing proteins to provide energy for the cell by regulating the transport of materials in and out of the cell Which structure can be found in both eukaryotic and prokaryotic cells? nucleus chloroplast nucleic acid mitochondrion Plant cells have a large membrane-bound space in which water, waste products, and nutrients can be stored. This space is called the vacuoles Golgi apparatus chloroplast mitochondrion What the defining characteristic of eukaryotic cells? irregular shape and size ability to respond ability to move presence of membrane bound organelles Which of the following is an example of a prokaryotic cell? amoeba bacterium virus liver cell The mitochondria are often called the "power house" of the cell. It's called that because it supplies energy for the cell to use. How does it do this? by using sunlight and converting light energy to chemical energy by using water stored in the vacuoles by using the proteins made by the ribosomes by converting glucose in to ATP molecules Samples of pond water taken over a six week period showed an increase in pH. During the same period, observation of the pond showed an increasing amount of green water plants covering the surface. Which cellular structure in green plants is likely a contributing factor to the increase in pH? mitochondria nucleus chloroplast cell wall
