Isotonic means____________________.
The solute particles are equal on both sides of the semipermeable membrane.
The cell cycle is essential to create new cells. To replace damaged old cells or repair wounds. The LONGEST phase of the cell cycle is___________.
What is INTERPHASE.
If you connect aa or (amino acids) together in a long chain you get a ____________.
What is a Protein or a polypeptide
This bond is called a sharing bond - but is shares the electrons unequally. At times, it is called an electron hog.
What is a polar covalent bond?
List the steps - that are taken when a transport vesicle arrives to the golgi apparatus.
What is
1. Receives transport vesicle (endocrine, mammary, digestive etc)
2. Modifies (membranes fuse opens )
3. Sorts the chemicals + repackages
4. Ships the packages to other parts of the cell
The movement of water - flows in or out of the cell?
In a cell with a 1% inside condition - placed in a beaker with 25% sugar solution.
What is --- OUT (the water flows out the the cell)
Briefly describe the phases of Mitosis...
Prophase - Chromatic coils into chromosomes
Metaphase- Chromosomes line up on equator
Anaphase- chromosomes pull apart into 2 sister chromatids
Telophase - nucleus reforms - chromosomes unwind.
Cytokinesis- 2 sep. cells
To make a polypeptide chain longer you ________
this process is called ______________-.
Remove water
Dehydration synthesis
Himalayan salt has this type of bond. Where electrons are transferred from one atom to another.
What is an ionic bond?
Why are cells so small?
What is the ability to allow oxygen and CO2 to diffuse across the membrane with ease. Yet, big enough to contain all the mechanical structures.
Discuss how Na2+ gets across the membrane?
Active Transport: Sodium potassium pump. It uses ENERGY in the form of ATP to move these across the membrane.
In the cell cycle there are check points (also know as STOPS) what is it called when these are ignored by cell growth_________________?
What is cancer.
To shorten a polypeptide chain ____________ this process is called _________________.
ADD water
Hydrolysis (think digestion- to break down)
