1
Q
Metabolism
A
- The set of chemical reactions that use energy from food to build substances the cell needs.
2
Q
Two Types of Metabolism
A
- Catabolism
• The breakdown of organic matter to obtain energy the cells need. - Anabolism
• Uses energy to construct components such as proteins and nucleic acids.
3
Q
Reproduction
A
- The production of offspring through asexual or sexual means.
4
Q
Cell Division
A
- Reproduction process by which the parent cell divides into two identical daughter cells.
5
Q
Cell Membrane (or) Plasma Membrane
A
- Separates the interior of the cell from the outside environment.
- Semipermeable
- Regulates the transport of materials entering and exiting the cell.
6
Q
Nucleus
A
- DNA Storage
7
Q
Mitochondrion
A
- Site of Cell Metabolism
- Converts energy(ATP) into a form the cell can use.
8
Q
Cytoplasm
A
- The jelly-like liquid that fills the inside of a cell
- Composed of water, salts, and various organic molecules.
9
Q
Ribosome
A
- The site of protein synthesis in the cell.
- A complex molecule made of ribosomal RNA molecules and proteins that form a factory for protein synthesis in cells.
10
Q
Golgi Apparatus
A
- Is responsible for transporting, modifying, and packaging proteins and lipids into vesicles for delivery to targeted destinations.
11
Q
Vesicles
A
- A small sac formed by a membrane and filled with liquid.
12
Q
Lysosome
A
- A membrane-bound cell organelle that contains digestive enzymes.
- Breaks down excess or worn-out cell parts.
- May be used to destroy invading viruses and bacteria.
13
Q
Chloroplast
A
- Plant cell organelles that convert light energy into relatively stable chemical energy via the photosynthetic process.
14
Q
Organelles
A
- Specialized structures that perform various jobs inside cells
- Serve specific functions to keep a cell alive
15
Q
Nucleolus
A
- An area inside the nucleus of a cell that is made up of RNA and proteins and is where ribosomes are made.
16
Q
DNA
A
- Deoxyribonucleic acid
- Is responsible for storing and transferring genetic information.
17
Q
RNA
A
- Ribonucleic acid
- Directly codes for amino acids and acts as a messenger between DNA and ribosomes to make proteins.
18
Q
Nuclear Membrane
A
- A double membrane layer that separates the contents of the nucleus from the rest of the cell.
19
Q
Enzymes
A
- Proteins that help speed up metabolism, or the chemical reactions in our bodies
- All living things have enzymes. Our bodies naturally produce enzymes.
- There are approximately 1300 different enzymes found in the human cell.
- All enzymes are proteins but all proteins are not enzymes.
