1What is the cell? The cell is a [blank_start]unit of life[blank_end]
- Aunit of life
2The Stanley Miller experiment was created to investigate how large and [blank_start]complex organic[blank_end] compounds were formed. It consisted of a [blank_start]closed system[blank_end] containing inorganic gases such as methane, ammonia and CO2 to represent a [blank_start]prehistoric[blank_end] earth atmosphere. He then added [blank_start]boiling water[blank_end] and heat.
The gases came [blank_start]together[blank_end] to form more complex organic molecules.- Acomplex organic
- Bclosed system
- Cprehistoric
- Dboiling water
- Etogether
3Spontaneous lipid assembly
- AFatty acids are hydrophobic
- BFatty acids are hydrophilic
- CFatty acids attach to hydrophilic phosphate groups
- DHydrophobic phosphate groups attach to fatty acids
- EPhospholipids form a bilayer
- FBilayers then form vesicles which are called micelles
- GPhospholipids form a monolayer
- HMonolayers create micelles
4We then need a [blank_start]controlled flow[blank_end] of molecules through the membrane via protein gates for sugars, amino acids ions and others.
- Acontrolled flow
5A cell must be able to [blank_start]replicate[blank_end] and divide, [blank_start]DNA[blank_end] is the cellular blueprint. It undergoes replication, transcription and translation.
Overall cells are a mix of macromolecules and small molecules surrounded by a membrane. The building plan is contained on DNA and multiplication is achieved by [blank_start]division[blank_end].- Areplicate
- BDNA
- Cdivision
6A bacterial cell is
[blank_start]30%[blank_end] chemicals
[blank_start]70%[blank_end] H2O
[blank_start]15%[blank_end] Proteins
[blank_start]6%[blank_end] RNA
[blank_start]4%[blank_end] ions and small molecules
[blank_start]2%[blank_end] phospholipids
[blank_start]1%[blank_end] DNA
[blank_start]2.%[blank_end] Polysaccharides- A30%
- B70%
- C15%
- D6%
- E4%
- F2%
- G1%
- H2.%
7CO2 (carbon dioxide) and N2 (atmospheric nitrogen) must be converted into [blank_start]organic[blank_end] form by [blank_start]photosynthesis[blank_end] and nitrogen [blank_start]fixation[blank_end]. [blank_start]Legumes[blank_end] fix nitrogen in their root [blank_start]nodules[blank_end].
• Nucleic acids: [blank_start]information[blank_end] storage and transfer
• Proteins: enzymes and [blank_start]structural[blank_end] proteins, [blank_start]transporters[blank_end], regulators
• Lipids: building blocks for [blank_start]membranes[blank_end], [blank_start]fat[blank_end], signalling
• Carbohydrates: Structural role, energy [blank_start]storage[blank_end], signalling
• Different energy sources: [blank_start]light[blank_end], organic and inorganic molecules
• Importance of CO2 and N2 fixation- Aorganic
- Bphotosynthesis
- Cfixation
- DLegumes
- Enodules
- Finformation
- Gstructural
- Htransporters
- Imembranes
- Jfat
- Kstorage
- Llight
