Cellular requirements Flashcards
To learn the basics of cells and know what they require to function
What is common to all cells? What do they need?
- Cells need energy
- Cells need matter
- Cells need simple nutrients
- Cells need simple molecules and Macromolecules
- Cells need to remove wastes
What is the primary source of energy used to drive thousands of chemical reactions occurring inside a cell?
Glucose
How do cells obtain energy?
Harnessing light energy to synthesise glucose = photosynthesis
What are Autotrophs?
Organisms that can photosynthesise to make their own food
What are Heterotrophs?
Heterotrophs are organisms that consume autotrophs to get energy
What are monosaccharides?
(Also known as Glucose) is the most basic form of carbohydrate. A foundation for more complex carbohydrates.
What are disaccharides?
When 2 monosaccharides join together. The most common form is sucrose, it is split during digestion into glucose and fructose.
What are polysaccharides?
When many monosaccharides join together. These are used for energy reserves in storage and for structural components.
What are amino acids?
The structural subunits required by a cell to build proteins.
What are nucleic acids needed to make?
DNA and RNA
