Cellular Biology: Key Processes and Structures
1 – Link 2 amino acids that binds: peptide bond (Figure 1). 2 – Formula cyclic glucose (Figure 2). 3 – DNA functions: it stores info. genetics, transmitter info. genetics, synthesis of specific proteins. 4 – Dendrite: elongation of the soma, many and complex branching, receive signals from other; Chondrocytes: cells in hollow cartilaginous gaps between the sust. intercellular fibers produce cartilage; Myelin: outer layer of cells lining Schwam, not isolate the nerve impulse across the cell lines of only a small part Schwam, tb is the white matter of the medula.5-Stomata: pores small plants located on the surface of their leaves. They consist of two great saves and stops cells surrounded by accompanying cells, regulate the entry and exit of CO 2 through the opening and closing thereof; Band Caspary: layer in the endodermis of the primary root structure in plants, impervious waterproofing the wall of the endodermis and prevents certain substances from entering it while allowing the passage of other substances necessary; Node of Ranvier: intervals along the length axon within the myelin sheath of the neuron unmicromero tiny spaces in length of the axon membrane exposed to extracellular fluid. 7 – bone tissue structure (Figure 3). 8 – Classification of plant tissue (Fig 4). 9 – Calyx: basal part consists of separate sheets x estaformada a single layer and its function is to protect the flower Androecium: stamen or male part, is formed x two bags containing the pollen, there are large or pekeños stamens or troops x down. 8 – Function of co2 in the opening and closing of stomata, if the concentration of solute is very high stomatal closing varies depending on the concentration of proteins and par. of golgi if the concentration is high the Esoma open. With the entry of CO2 in the plant the concentration varies. This allows the transpiration of the plant. 9 – The plants have thousands of xylem vessels instead of one very large because the xylem ak need to reach all parts of the plant and with a tube that would not be possible muygrande while k with thousands of tubes can reach side cuelkier of the plant. 10 – Intervention of water in photosynthesis: eater is stimulated x sunlight, the H2O is broken and divided into 1 / 2 O2 and 2H by photolysis, electrons are released ke cover the loss of P680, H protons cover the absence of NADP, is formed then one molecule of NADPH +. 11 – Calvin cycle (drawing 5). 12 – Double fertilization of angiosperms: When the flowers polenllega fem. is retained, there goes 3 months divides and forms the male gametophyte nuclei will lead to fertilize ovosfera yse, 1 year, pollen trans x the wind carries a seed falls to the ground ygermina k, the seed goes long dormant seasons to find the momnto germinate. What remains dormant klas sonuna fitamonas molecules regulating x elclima, the walls are broken x k enzymes create a channel and ends up breaking. 13 – The state of lethargy produced x a series of hormones that chemical inhibition of germination in response to the t th and light. This is to protect the seed of environmental features 14 – the endosperm is used as a source of nutrients for the embryo during the germination period, occurs inthe female embryo sac of the flower. 15 – Drawing stoma (drawing 6) 16 – inspiration and expiration: inspiration: As the pressure of the atmosphere and the lungs is different, there is more pressure and x inthe atmosphere that comes elaire to balance the 2 pressures, thoracic theFund enlarges and intercostal muscles contract. Expiration: the diaphragm and intercostal muscles relax, allowing the chest to shrink the x prsion is less so the air comes out 16 – is produced and synthesized in the chloroplasts, or n increase in the concentration of this hormone in response to leaf water stress causes stomatal closure, transpiration decreases, inhibits plant growth and development of seeds and fruits are transported through the xylem. 17 – Types of air into the lungs (drawing 7) 18 – pancreatic juice: is produced in the pancreas, is formed x water (solvent), pancreatic amylase (starch degrades and passes glucosidicosy links or ls-carbohydrate to monosaccharides), lipase pancreatic (breaking down fat), trypsinogen and quimiotripsinogeno (Sust. activated in trypsin and chymotrypsin and degrade the last oligopeptides) and pancreatic nuceaves (nucleic Links Important degrade proteins)
