SOLUTIONS GRADED A+
• E.
Answer:
• key example of secondary active transport.
Answer: glucose, amino acids
• A.
Answer:
• B.
Answer:
• dynein.
Answer: carries cargo toward the MINUS ends of the microtubules
• why is pH important?.
Answer: ensures polar head is in ionized form--makes them hydrophilic
• A.
Answer:
• A.
Answer:
• rough ER.
Answer: studded w/ ribosomes (protein synthesis)
• A.
Answer:
• C.
Answer:
,• can microtubules grow by addition/shorten by removal of tubulin dimers
from both plus AND minus ends?.
Answer: yes
• B,D,F.
Answer:
• mitochondria.
Answer: chemical factories that produce energy - converts sugar --> energy
(ATP) - cellular respiration - has an outer/inner membrane but is NOT a part
of endomembrane system
• B,C.
Answer:
• B.
Answer:
• osmolarity.
Answer: concentration of solutes in a solution
• 3 major support structures of the cell.
Answer: 1. cytoskeleton 2. cell junctions 3. extracellular matrix
• C.
Answer:
• C.
Answer:
• example of prokaryotes.
Answer: bacterium, archaeon microbes
• B,D,E.
Answer:
• myosin.
Answer: present in muscle fibers that aids in contraction & makes up the
majority of muscle fiber
, • diffusion.
Answer: movement of ALL SUBSTANCES from an area of higher
concentration --> lower concentration
• 2 types of membrane transporters.
Answer: 1. channel 2. carrier
• C,E.
Answer:
• receptor-mediated endocytosis.
Answer: type of endocytosis where receptor proteins on the cell surface are
used to capture a specific target molecule - enables a cell to acquire bulk
quantities of specific substances (rare) - coated pit helps give vesicle its
rounded shape
• keratinocytes.
Answer: specialized epithelial cells that whose function is to protect
underlying tissues/organs
• sodium-potassium pump.
Answer: a CARRIER protein that uses ATP to actively transport sodium
ions (Na+) out of a cell & potassium ions (K+) into the cell - 3 sodium for
every 2 potassium - goes against concentration gradient (more sodium
outside of cell, more potassium inside of cell) - helps w/ homeostasis
• unsaturated fats.
Answer: - carbon=carbon double bonds - kinked structure - reduced
tightness of packing --> enhances mobility (fluidity)
• C.
Answer:
• dermis.
Answer: inner layer of skin - contains fibroblast cells in connective tissue -
contains arteries, nerves, veins, sweat glands (supports epidermis)
• example of the organization of cells, tissues, & organs relating to function.
