Cells
Network of fibers-organises internal structure
What is cytoskeleton?
Lipid bilayers allow some things to pass through more easier than others
What is Selective permeability?
This is the reproduction for bacteria
What is binary fission?
What is antiparallel strands?
This pathway releases energy by breaking down complex molecules to simpler molecules, like oxidation of glucose during cell respiration
What is a Catabolic pathways?
This cell part functions to do protein synthesis
What are ribosomes?
Solute concentration on the outside is greater than the solute on the inside
What is hypertonic?
This is the dividing phase of the cell
What is the mitotic phase?
This is known as the smaller nucleotide base.
Consists of Cytosine and Thymine.
What is Pyrimidines?
Uses energy to build complicated molecules from simpler ones, eg synthesis of sugars during photosynthesis or polymers from monomers
What is Anabolic pathways?
They are biological surfaces and consist of a phospholipid bi-layer with various proteins attached
What is a Plasma membrane?
Ions are charged so they move in response to a combined electrical and chemical gradient called this
What is electrochemical gradient?
Using DNA nucleotides and using DNA as a template, a copy of DNA is made
What is DNA replication?
This enzyme breaks, swivels and rejoins DNA relieving strain of unwinding
What is Topoisomerase?
This reaction type is spontaneous, and energy is released
eg Cellular respiration
What is a exergonic reaction?
In cells, the organization of microtubules in a eukaryotic cell with kinesin and dynein motor proteins help with this.
What is cell motility?
Theses proteins change shape to move molecules across the membrane
What is carrier proteins?
This captures and moves the sister chromatids by binding to the kinetochore
What is Kinetochore microtubules?
This enzyme seals the free end of the new DNA to the old DNA
This also forms a bind between fragments to complete DNA strand.
What is DNA ligase?
This is the term used for the addition of a phosphate group to a protein or other organic molecule
What is Phosphorylation?
the nuclear envelope is supported by a lattice-like sheet
What is the nuclear lamina?
Have a "water loving" end and a "water hating end"
What is Amphipathic phospholipids?
Sister chromatids are held together at this place in the cell and by the cohesion proteins
What is the centromere?
This is a repetitive, non coding nucleotide sequences at the end of DNA which act as protective caps
What is telomeres?
A molecule similar in shape and size binds to the ACTIVE site is called this type of inhibition.
What is competitive inhibition?
