Cell Membrane Parts
The phosolipid has ________ and 2 _______
Head and 2 Tails
This type of transport moves molecules from high to low concentration without using energy
Diffusion
Starch is Big Glucose is small
What is concentration gradient?
How much solute in a solution from one side compared to another
Building blocks of proteins
Amino Acids
This part allows other cells to identity what cell to send a message to
Carbohydrate chain
The process of water moving across a cell membrane
osmosis
What was the purpose of iodine
Starch indicator solution
The condition when solute concentration is the same inside and outside the cell
Isotonic
The absorption and distribution of materials within an organism is a life function known as
These specialized proteins help molecules move across the cell membrane.
Integral Proteins
Transport that requires ATP and moves molecules against their concentration gradient
Active Transport
We placed onions in salt water, what happened to the cell wall, cell membrane and cytoplasm
Cell membrane and cytoplasm shrunk
cell wall remained the same
Why is it important organic macromolecules be digested for the human body?
Complex to Simple
Hydrolysis
no bc most of the cell is hydrophobic
This cellular process involves engulfing liquid
Pinocytosis
What is the indicator we used for testing glucose
In order to survive in its environment, a single-celled organism uses a contractile vacuole to remove excess water that diffuses into its cell. What type of environment does this organism live in, explain
Fresh water bc there is more water outside and the water will diffuse in
A small lizard spends the morning hours lying in the sunlight until its body temperature rises. Later on in the day, the lizard rests in a shady area until its body temperature cools. This type of behavior is important to
Homeostasis
When a cell is placed in this type of solution, it will swell and potentially burst.
hypotonic
The specific type of diffusion that uses protein channels to help molecules cross the membrane.
Facilitated Diffusion
How was the dialysis tubing similar to a cell membrane
In the human body there is a potassium sodium pump on our cell membrane that allows for these materials to go against the concentration gradient to find the optimum levels this allows the cell to maintain
homeostasis
illustrate the increasing complexity of levels of organization in multicellular organisms?
organelles, cell, tissue, organ, organ system, organism
