Give an example of disease involving malfunction of proteins
viruses, cancer, Alzheimer's, and Mad Cow
What is Homeostasis?
Homeostasis is the tendency to maintain stable equilibrium of physiological processes
What is Osmosis?
the movement of water through a cell membrane
Give an example of diffusion :)
Active Transport, Passive Transport, Osmosis, and Waste Removal
What is cellular respiration?
Occurs in the mitochondria of eukaryotes, the cytoplasm of prokaryotes. In the process, oxygen is consumed and carbon dioxide is generated.
What is protein synthesis?
a process within a cell in which amino acids are joined together to make a protein.
It requires a messenger RNA and takes place on ribosomes.
What is mitochondria?
cell organelle that convert glucose into energy (ATP)
what is active transport?
The movement of ions or molecules across a cell membrane into a region of higher concentration, assisted by enzymes and requiring energy.
What is photosynthesis?
Uses sunlight to synthesize foods from carbon dioxide and water.
What are the two main stages of protein synthesis in order?
transcription (mRNA) and translation (tRNA)
What is Chloroplast?
Organelle of plants and some other organisms use energy from the sunlight---photosynthesis
What are ribosomes?
organelle that synthesise proteins
what is passive transport?
transport of a substance across a cell membrane by diffusion; expenditure of energy is not required.
what is fermentation?
Anaerobic breakdown of a substance by bacteria, yeasts, or other microorganisms, typically giving off carbon dioxide and Hear
what is the nucleus?
large structure inside some cells that contains the cell's DNA and controls the cell's carbs.
what are lysosomes?
an organelle in the cytoplasm of eukaryotic cells containing degradative enzymes
What is chemosynthesis?
Using energy derived from reactions involving inorganic chemicals (Rocks), typically in the absence of sunlight.
Why is protein synthesis important for living systems?
Without protein synthesis, living things could not grow or heal itself.
What is the purpose of homeostasis?
regulates its internal environment and tends to maintain a stable, relatively constant condition of properties such as temperature or pH.
What is Mad Cow Disease?
is a fatal, neurodegenerative disease in cattle, that causes a spongy degeneration in the brain and spinal cord
