at this post we brief little give tutorial about cell structure, why because in 1995 until now cell always have the own number at UMPTN or SPMB test sheet,
see and learn carefully biological cell structure below

here we explain some parts of cell thats are

Golgi Apparatus
Structure

• stacks of flattened sacs of unit membrane (cisternae)
• vesicles pinch off the edges

Function

• modifies chemicals to make them functional
• secretes chemicals in tiny vesicles
• stores chemicals
• may produce endoplasmic reticulum

Ribosome

Structure

• non-membraneous, spherical bodies composed ofv RNA (ribonucleic acid) and protein enzymes

Function

• site of protein synthesis

Mitochondrion

Structure

• composed of modified double unit membrane (protein, lipid)
• inner membrane in folded to form cristae

Function

• site of cellular respiration ie. the release of chemical energy from food

The first law of thermodynamics is the application of the conservation of energy principle to heat and thermodynamic  can be  define by this formula

this a basic enthalpy equation, enthalpy can be define by potential energy of thermodynamic,  SPMB test 2004 in chemistry major  have  some number which contains enthalpy problem, beside larutan, nitrogens,fertilizer  chemistry (pupuK) asam-basa reaction, and core reaction.chemistry problem for SPMB 2004 have 15 number.
