The working cell
What tonic solution is best for plant cells
Hypotonic solution
what are the two main forms of energy?
Kinetic and potential
is cellular respiration aerobic/anaerobic
aerobic
What are the 3 stages of cellular respiration and which DOES NOT NEED OXYGEN
glycolysis (can be anaerobic)
Krebs
oxidative phosphorylation
What stage makes the most ATP
oxidative phosphorylation
What is the difference between active and passive transport?
Active takes energy, passive does not
What are the waste products of both cars and humans in entropy increasing energy transformations
CO2 + H2O
what two processes work hand in hand for the energy of life
cellular respiration and photosynthesis
Net products of glycolysis and how many ATP are used to start the process
2 ATP used, glucose is split to 2 G3P
Makes 4 ATP, 2 NADH, 2 Pyruvates
cohesion- molecules stick to themselves
adhesion- molecules stick to different molecules
What are the two kinds of endocytosis and what do they mean?
Phagocytosis-particles are engulfed
Receptor mediated-receptors in plasma membrane bind to specific solute
Match what goes together
Catabolic/Anabolic
with
Endergonic/exergonic
which builds up molecules and which breaks down
Endergonic + anabolic builds up
Exergonic + catabolic breaks down
how many atp does a muscle cell use per second
10 million
What is the fate of pyruvate to start Krebs cycle?
Enters the mitochondrion through transport protein
1. Oxidized to acetate + CO2
2. NAD+ is reduced to NADH
3. Acetate + Coenzyme A → Acetyl- CoA
dehydration reactions / hydrolysis reactions
which forms new bond and which breaks a bond
dehydration forms
hydrolysis breaks
What facilitates diffusion across the membrane?
Transport proteins
What do enzymes do and HOW
speed up reactions by lowering energy barriers/activation energy
oxidation is __ of __
reduction is __ of __
loss, electrons
gain, electrons
how many turns does glucose do for Krebs cycle
2
What is the functional unit of life
cells
What is the difference between competitive and noncompetitive inhibitors and draw it
competitive fight with the solute to bind to active site
noncompeitive- bind to allosteric site
What common drug used is an enzyme inhibitor
ibuprofen
what is the cellular respiration formula
glucose + 6 O2--> 6CO2 + 6H2O + 32ish ATP
what is generated in Krebs cycle
NADH FADH2 and ATP
which way do the heads and tails face in phospholipids
head out tail in
