Aerobic respiration |
Enzyme controlled process which requires oxygen to produce energy from the breakdown of glucose Glucose +oxygen >co2 +water +atp |
|
Atp |
Is the energy carrier molecule in all living cells |
|
Chloroplast |
Organelles found in plant cells which is the site of photosynthesis |
|
Denature |
To alter the shape of a protein (enzyme) by breaking the band's holding it together. This renders it unable to carry out it's function |
|
Endoplasmic reticulum |
Network of membranes involved in processing proteins (rough er) and lipids (smooth er) |
|
Golgi body |
Network of folded flattened membrane found in the cytoplasm of cells which are involved in packaging protein molecules |
|
Lysosome |
Sack like organelles which contains digestive enzymes they are involved with the digestion of cellular invaders and waste molecules. |
|
Mitochondria |
Organelles found in the cells which is the site of respiration (aerobic ) |
|
Ribosome |
Small organelles found in the cell on roughER which is the site of protein synthesis |
|
Photosynthesis |
Enzyme controlled process occurring in plants that use energy from sunlight to convert c02 +h2o > glucose |
|
In the cell cycle what happens during the m phase |
Mitosis the replicated chromosomes separate |
|
What happens during phase g1 during the cell cycle |
Cell contents grow |
|
What happens during s in the cell |
DNA replication |
|
What happens during phase g2 of the cell cycle |
Checking for mutations |
|
Photosynthesis formula |
H2o + CO2 >C6H12O2 +O2 +atp |
|
What is the purpose of photosynthesis |
To create glucose which is converted into energy needed to carry out life process |
|
What is a thylakoid |
Are flattened disks containing chlorophyll located in the chloroplasts |
|
What is a grana |
A stack of thylokoids |
|
How does chloroplasts carry out it's function effectively |
It is rod shaped which decreases the distance for diffusion thus increasing the rate of reaction Thylakoids are thin and flat in stacks to increase surface area ... Double membrane allows compartmentalisation which means chloroplast can be in optimum conditions for enzymes to work to ^ rate of photosynthesis |
|
What is compartmentalisation |
Provides multiple compartments therefore different environmental conditions such as ph can occur so enzymes can work in optimum conditions the increase the rate of reaction |
|
What is this? Label |
Chloroplast |
|
Calvin cycle |
Carbon dioxide and hydroden from the water are bonded together this process is light independent this is also known as the dark cycle |
|
Primary structure |
a sequence of amino acid bonded by poly peptides |
|
Secondary structure |
Can be alpha helix or beta sheet Alpha is in a helical path that is held in place by hydrogen bonds Beta shets strands of protein adjacent to one another a d are held in place by hydrogen bonds between peptide backbones |
|
Tertiary structure |
Structure starts folding and is held together by salt bridges and bonds |
|
What is mrna and what does it do |
rna Messenger rna Because DNA can not exit the nucleus due to its size therefore mrna Because DNA can not exit the nucleus due to its size therefore mrna |
