Ch. 5
What macromolecule makes up a majority of the plasma membrane? (2 bonus points if you describe the parts)
Phospholipid (hydrophilic head and hydrophobic tails)
Photosynthesis converts __________ to ___________
light energy to chemical energy
What types of reactions do we use in cellular respiration?
redox reactions
What is being produced in photosynthesis?
Sugar (specifically glucose)
What is the main function of DNA that is the focus of this chpater?
Replication
We describe the phospholipid bilayer as _________________ (2 bonus pts. if you can describe why it is called this)
a fluid mosaic model (phospholipid bilayer is surrounded with water and made up of different parts such as carbs, proteins, etc.)
What type of energy would a rock sitting on the top of the hill contain?
potential energy
In the breakdown of pyruvate stage, what are the beginning and ending products and reactants?
beginning- 2 pyruvate
ending- 2 acetyl CoA and 2 NADH
Autotrophs (make their own food)
What direction does DNA replicate?
5 to 3 (ALWAYS)
What molecules can easily pass through the membrane?
nonpolar (uncharged), small molecules
What are the three types of work?
mechanical, chemical, and transport
True or False: The Electron Transport Chain does not require oxygen in order to operate.
False: it needs oxygen (fermentation would occur if there was not oxygen)
What absorbs sunlight in plants? (1 bonus pt. for naming most popular & 1 pt. for where they are located)
pigments (chlorophyll a & in mesophyll = middle of the leaf)
What do you think will glue broken fragments?
a. DNA Ligase
b. DNA primase
DNA ligase
What type of transport does this describe:
Oxygen moving from our lungs to tissues
passive transport
What is the structure of ATP? (2 bonus pts. if you tell me what reaction is used to make + break ATP)
Adenine (nitrogenous base), ribose sugar, and 3 phosphate groups (dehydration = make and hydrolysis = break)
What kind of transport is needed to:
- bring oxygen into the body
- glucose through the cell membrane
- turn the ATP synthase to make ATP
- passive transport
- passive facilitated transport
- passive facilitated transport
True or False: The color visible in plants is the pigment that is not absorbed.
True
True or False: Enzymes are used during replication.
True
True or False: If something is hypertonic, there is less solute in the surrounding environment.
False! Goes fro low solute to high solute, so if it is hypertonic, the surrounding environment should have the most solute.
True or False: Enzymes are highly specific and reactive and use the lock and key model.
False: utilizes the induced fit model
Why are we given a range of how much ATP is made?
Some ATP may need to be used to assist molecules in some of the cycles (ex. Glycolysis + Acetyl CoA formation)
What are the 2 stages of photosynthesis?
Light Reactions and Dark Reactions (Calvin Cycle)
Why do you think a DNA strand is called semi-conservative?
Half from original DNA and half from new DNA
