physiochemical substancee Flashcards
a water-based solution that serves as the ground substance to where the organelles are suspended
cytosol
organic compounds in the cytoplasm
carbohydrates, fats, and proteins
inorganic compounds in the cytoplasm
water carbon dioxide minerals and electrolytes
Polyphasic Colloidal System
contains water
solutes are dissolved
Irritability
Reacts or responds to stimuli
viscosity
state of being thick,
sticky, semifluid
Gel: Semi-solid
Sol: Semi-liquid
Specific gravity
slightly above water
Streaming movement
cytolosis, movement of the fluid substance
ph
6.8 slightly acidic
Most abundant among the organic compounds
Main compositions are Carbon (C), Hydrogen (H), and Oxygen (O)
Store and transport energy
Structural elements in animal and plant cells
Produced during photosynthesis
Carbohydrates
Sources of energy
Repair and building of body tissues
Amino acid
17% of the mature human body is composed of proteins
Hormones, enzymes, immune molecules
Protein
Fats: solid form; Oils: liquid forms
Provide energy
Form structural materials of cells and tissues
Conserve water or to avoid desiccation
Thermal insulator; Maintain body temperature
Protect internal organs
Glycerol and Fatty acids
lipids
Most important molecule in f]genetical aspect
DNA: contains the hereditary material
RNA: for protein synthesis
Nucleotides
nucleic acids
As nutrient constituent to maintain life processes
As trace or macro-elements into the body
7% of the body weight is by minerals
*The elements needed in higher amounts are known as macro elements and the elements needed in small amounts are known as trace elements
minerals
Needed for activities of the human body
Oxygen: for energy production
Carbon dioxide: for the process of photosynthesis
Gases
