Cells & Biochemistry

Living Environment Packet 2

Levels of Organism cells -> tissues -> organs -> organ systems -> organism
Life Processes growth, excretion, nutrition, transport, synthesis, respiration, regulation, reproduction
Excretion getting rid of waste (ex: exhale, sweat, urine)
Respiration O2 + nutrients = ATP (energy)
Synthesis small to big molecules (ex: glucose -> starch)
Metabolism how much energy you use
Homeostasis balance of body systems
Regulation endocrine & nervous system
Heterotroph ingests food
Autotroph makes food
Prokaryote no nucleus
Eukaryote has nucleus
Multicellular many cells
Unicellular one cell
Organ collection of tissues (large)
Organelle inside cell (small)
Chloroplast where food is produced
Chlorophyll where photosynthesis takes place
Cytoplasm found in between organelles
Ribosome makes protein
Rough ER has ribosomes attached for protein synthesis
Smooth ER produces lipids
Golgi Apparatus stores, modifies and ships proteins
Cell Membrane boundary of the cell
Lysosome breaks down wastes using enzymes
Mitochondria where cellular respiration occurs (makes ATP)
Nucleus holds the DNA
Vacuole storage container
Cell Wall provides a rigid shape for the cell
Centriole aids in cell division
3 elements that make up organic compounds carbon, hydrogen & oxygen
Carbohydrates Building Blocks glucose
Function of Carbohydrates quick energy
Examples of Carbohydrates glucose, lactose, fructose, sucrose
Formula of Glucose C6H12O6
Shape of Glucose ring-like structure
Lipids Building Blocks glycerole & 3 fatty acids
Function of Lipids stores energy
Examples of Lipids fats & waxes
Building Blocks of Proteins chains of amino acids
Function of Proteins communication, support & movement, helps fight disease
Examples of Protein enzymes, antibodies, hormones
Enzymes catalyst/speeds up chemical reaction
Building Blocks of Nucleic Acids nucleotides
Function of Nucleic Acids holds genetic material
Examples of Nucleic Acids RNA, DNA
Disaccharide a sugar formed when two monosaccharide molecules are joined
Monosaccharide simple sugar such as glucose
Polysaccharide complex carbohydrate such as starch
Hormone produced by endocrine glands - sends messages
Antibodies fights infection against pathogens
pH measure of the amount of acid or base present
ose carbohydrate
ase protein
2 Types of Passive Transport Diffusion and Osmosis
Diffusion High --> Low concentration
Osmosis Movement of water from High --> Low
