|
the rate of diffusion is directly related to
|
the SA:V
|
|
|
the lower the SA:V ratio the
|
lower the rate of diffusion
|
|
|
diffusion of materials increases or decreases with a large area
|
increases
|
|
|
diffusion of materials increases or decreases with a small pressure gradient
|
decreases
|
|
|
diffusion of materials increases or decreases with a large distances
|
decreases
|
|
|
in ficks law of diffusion the A in K* A* (P2-P1)/D means what?
|
surface area
|
|
|
what is something that increases A in the human body in Ficks law
|
villi, microville
|
|
|
D in fick's law represents what?
|
how thick the area to be passed through is
|
|
|
the metabolic rate of mamals is indriectly related to size why?
|
because the larger the mammal the more heat they lose
|
|
|
when you place a cell and water on the same plate what happens?
|
through osmosis the cell will grow as it takes on water
|
|
|
what will happen if you add salt to a cell in a petry disk?
|
the cell will shrink because the salt will take the water out of it
|
|
|
what is the relationship between ATP and glucose?
|
glucose is used to store energy that upon its break down releases ATP
|
|
|
pyruvate processing does what and occurs in what?
|
it occurs in cellular respiration and it couples acetyl coA to glycolisis
|
|
|
the stroma is the site of what
|
light-independent phase of photosynthesis
|
|
|
what output of light dependent reaction is used as an input for the light independent reaction in photosynthesis?
|
ATP
|
|
|
what is meant by the term CO2 fixation?
|
that CO2 has been bound to an organic molecule
|
|
|
what are carotenoids
|
an organelle found in plant leaves that captures different wavelengths from light than cholorphyll does
|
|
|
what are the six challenges that organisms faced when moving from water to land?
|
obtaining food, gas exchange, structural support, reproduction, senses, water retention and distribution
|
|
|
why is the root and shoot system almost exclusively unique to land plants
|
plants in water can obtain what they need from the water around them
|
|
|
how did the explosion of land plants effect the atmosphere
|
increase of O2 loss of CO2
|
|
|
how do fish ventrilate their gills?
|
the increase the water pressure in their mouth throat and gills sucking the water in and across their gills
|
|
|
what is it harder for gills to obtain oxgen than lungs
|
water has a higher vesocity making it hard to extract the O2 from it than air does
|
|
|
as blood moves away from the heart blood pressure decreases why?
|
the vessels become thinner and smaller, pressure must decrease so as not to bust the vessels
|
|
|
what are the names of the closed 2 circulatory systems in vertebrates?
|
pulmonary and systemic
|
|
|
what is a closed system (relating to circulation)
|
it means that no matter where you start you can eventually get back to that start
|
|
|
why do humans have two separate circulatory systems
|
easier to separate the blood that needs oxygen from those that contains oxygen
|
|
|
the pulmonary system carries what
|
oxygenated blood
|
|
|
the pulmonary veins enter into what side of the heart
|
the left side more specifically the left atrium
|
|
|
what are the inputs of cellular respiration
|
glucose,oxygen, adp and pi
|
|
|
what are the outputs of cellular respiration
|
CO2, H2O, ATP
|
|
|
what are the inputs of photosynthesis
|
CO2, H20, LIGHT
|
|
|
what are the outputs of photosynethesis
|
glucose, oxygen and water
|
|
|
what is the light dependent part of photosynthesis
|
changes light into chemical energy
|
|
|
what are the inputs of the light dependent part of photosynthesis
|
water and light
|
|
|
what are the outputs of the light dependent part of photosynthesis
|
ATP and NADPH and O2
|
|
|
what are the products of the kalvin cycle
|
glucose and other carbs
|
|
|
what are the inputs of the kalvin cycle
|
ATP and NADPH and CO2
|
|
|
what is the purpose of the light independent phase oh photosynthesis
|
change chemicals into carbohydrates
|
