SubCellular Structure
DNA, RNA, LIPIDS, PROTEINS
What are macromolecules?
Light dependent reactions (AKA: Photosynthesis) take place here
What is the Thylakoid?
Water moves from
What is High water potential to low water potential?
Organelle that fuses with product from phagocytosis
What is Lysosomes?
Phagocytosis is cellular eating. The food vacuole that is formed needs to be digested, thus it will fuse with lysosomes to be digested.
Passive transport
What is does not require input of energy and moves with gradient?
Type of membrane protein allows water passage
A. Carrier protein B. Channel protein
What is Channel protein?
Synthesizes cytosolic proteins
What are Free Ribosomes?
Light independent reactions (also called dark reactions or the Calvin-Benson cycle) take place here
What is the Stroma
Extracellular solution is isotonic, direction of water movement
What is BOTH into and out the cell?
Makes up cell wall of plants
What is Cellulose?
The cell wall of plants is made up of cellulose, a structural polysaccharide
Active transport
What is requires input of energy and moves against gradient?
Membrane protein allows water passage
What is aquaporin?
Water passes through a channel protein called an aquaporin. Channel proteins act as a tunnel to allow materials to pass from one side of the membrane to the other side of the membrane.
Sorts, modifies, and packages protein products
What are Golgi Bodies?
Thylakoids organized into
What are small sacs organized in stacks called grana?
The higher the solute concentration…
What is the lower the water potential?
Dr. Crystal Bonds
Who is the former principal of HSMSE?
Facilitated diffusion
What is uses transport proteins and is a type of passive transport?
Facilitated diffusion
What is uses transport proteins and is a type of passive transport?
Intracellular digestion
What are Lysosomes?
Intracellular transport, Mechanical support, Protein synthesis
What are the roles of Rough ER?
Organelle that function with plant cell in hypotonic solution
What is the Central Vacuole?
Address of HSMSE
What is 240 Convent Avenue?
Pressure potential = 0.2 MPa and solute potential = - 0.6 MPa…
Ψ = ΨS + ΨP
Water Potential = -0.4 MPa
small & polar substances cross the membrane by
What is Transport proteins?
These are transmembrane proteins with a hydrophilic region interior to allow a channel or active site to bind to the solute to carry across.
Name the three types of RNA and their functions
What is mRNA (messenger RNA) is the RNA transcript synthesized from the DNA template? T
What is rRNA (ribosomal RNA) is the RNA that comprises the ribosome. It binds with protein to make the ribosome?
What is tRNA (transfer RNA) will transfer amino acids to the ribosome to allow for translation?
When a cell breaks down its nucleic acids and proteins and becomes engulfed by macrophages
What is apoptosis?
Extracellular solution is 0.5M and the cell is 1.0M – an animal cell will
What is Lyse?
Number of female STEM teachers at HSMSE
What is 3?
Process by which oxygen enter blood cells in the lungs
What is simple transport?
Which does NOT have a cell wall?
A. Fungi
B. Plants
C. Prokaryote
D. Protist
What is Protists?
Fungi, Plants, and Prokaryotes have cellwallsaroundtheir cells. Fungi has the carbohydrate chitin, plants have the carbohydrate cellulose, and someprokaryoteshave the carbohydrate peptidoglycan.
Cellular eating, use pseudopod to engulf food
What is Phagocytosis?
Phagocytosis isthe actof cellular eating. The pseudopods surroundthe foodparticle forming the foodvacuole which fuses withthe lysosome.
Prokaryotes have regions with specialized structures and functions:
True or false
What is true?
Organelle functions with freshwater protists
What is Contractile Vacuole?
number of children Dr. Asamani has?
What is 2?
Process by which Ca2+ move across membrane from high to low
What is facilitated diffusion?
Exocytosis
What is a process for moving large molecules out of the cell to the cell exterior?
Cellular drinking, cell “gulps” extracellular fluid
What is Pinocytosis?
Pinocytosis is the act of cellular drinking. The membrane undergoes invagination to bring in extraceullar-fluid and solutes.
eukaryotic vs. prokaryotic cells differ in terms of compartmentalization
Answers differ
What is eukaryotes are bigger?
What is eukaryotes have membrane bound organelles?
etc...
Extracellular solution is 0.5M and the cell is 1.0M – water will flow be
What is into cell towards hypertonic solution?
Next AP Exam date by college board
What is Thurs - May 16, 2024?
Endocytosis
What is requires ATP and allows large particles to enter the cell?
Describe the orientation of phospholipids & how that contributes to permeability.
What is the membrane is made up of a double layer of phospholipids. The phosphate heads associate to the extracellular and intracellular regions while the fatty acid tails associate to the interior of the membrane?
