1. Fertilization
*Recognition:* Sperm produces protein to bind to receptor molecules on glycoprotein layer of oocyte. (Vitelline layter insures that fertilization occurs only between egg and sperm) *Penetration:* Sperm and oocyte fuse *Formation of fertilization membrane*: Vitelline layter forms a membrane to block additional sperm. *Completetion of meiosis 2:* Sperm penetration triggers meiosis 2 to produce ovum and polar body *Fusion of nuclei and replication of DNA:* Sperm and ovum nuclei fuse (Diploid)
Steps in Clotting Cascade
*Tissue is damaged.* This tears blood vessel walls which exposes collagen that is within the wall. *Exposed collagen* in the circulating blood causes the platelet activation and platelets begin to adhere and aggregate in the area of the blood vessel where the rip has occurred. This forms a *platelet plug.* Activated platelets release *thromboplastin* (also known as tissue factor). Thromboplastin converts the precursor (inactive) *prothrombin into its active form, thrombin.* Activated thrombin converts precursor *fibrinogen to fibrin*. Fibrin strands polymerize with other fibrin strands, and attach to platelets to form a blood clot (hemostatic plug).

C4 Photosynthesis - Cugarcane - Corn - Crabgrass
- Add on feature to calvin cycle (C3 photosynthesis) 1. CO2 enters leaf in mesophyll cells and combines with PEP (Phophoenolpyruvate) to create OAA (Oxaloacetate - 4 carbons) - PEP carboxylase is enzyme. 2. OAA is converted to malate. 3. The malate is shuttled to a bundle sheath cell with a plasmodesmata. 4. Malate is converted back to pyruvate and CO2. 5. CO2 is left in bundle sheath cell and pyruvate (ATP --> AMP) is taken back to the mesophyll cell. PURPOSE: Get CO2 to bundle sheath cells because there is little O2 there. - Higher photosynthesis rate - Less water loss from stomata - PEP has lower affinity for O2 so it prevents photorespiration DAT BOOTCAMP This method is called C4 photosynthesis because the CO2 molecule integrates into and becomes a four carbon compound first, before it bonds to RuBisCO later on. PEP carboxylase has even lower affinity for O2 compared to RuBisCO, so even in the presence of O2, it is very unlikely to bind to oxygen. This is an advantage. The enzyme PEP carboxylase takes CO2 and converts it into oxaloacetate. Oxaloacetate quickly turns into malic acid. Both oxaloacetate and malic acid are four carbon compounds, hence the name C4. The malic acid will be transferred from the mesophyll cells where PEP carboxylase reaction has occurred, to the bundle sheath cells. The bundle sheath cells are located in a different area in the leaf anatomy (they surround the vascular bundles of plants), where O2 concentration is much lower. Here the malic acid can be decarboxylated to release CO2. The CO2 can now undergo the conventional Calvin cycle with RuBisCO, in an environment where O2 is not as prevalent, and RuBisCO has low risk of photorespiration. The C4 photosynthesis process isolates CO2 spatially. Spatial isolation means that CO2 is transported to a different location (a different space) to prevent photorespiration. C4 photosynthesis transports the CO2 to the bundle sheath cells.

CAM Photosynthesis (Crassulacean Acid Metabolism) - Cacti
1. PEP carboxylase fixes CO2 to OAA (Oxaloacetate - 4C). 2. OAA is converted malic acid. 3. Malic acid is shuttled to the cell vacuole. (Accumulates during night) 4. During day, malic acid is shuttled out of the vacuole and converted back to OAA (ATP converted to ADP) and releasing CO2 for calvin. DAT BOOTCAMP CAM plants use temporal isolation. Temporal isolation is an isolation based on timing, as a means of preventing photorespiration. There is no spatial separation: the processes occur in the same part of the leaf, but the plant does different processes at different times. During the day, CAM plants close stomata to prevent excessive loss of water, via transpiration, evaporation out of the stomates (keep in mind this will also limit new gases like O2 from entering the plant). At night, CAM plants have their stomata open, allowing CO2 to enter into the leaf. The same enzyme in C4 photosynthesis is used in CAM photosynthesis: PEP carboxylase will fixate CO2 into a four carbon molecule of oxaloacetate which converts into malic acid. In contrast, to the C4 pathway, rather than shuttle the malic acid to a different part of the leaf, the malic acid will be stored in a vacuole, for later use. During the day, the malic acid will be shuttled out of the vacuole, CO2 will be decarboxylated from the malic acid, and the typical Calvin cycle will occur in a low O2 environment (stomates are closed). During the day the sun shines brightly, and ATP as well as NADPH are being produced plentifully.

Difference in vessels
Arteries: - Contain smooth muscle that can contract or relax, changing their diameter in response to hormones. - Carry and distribute oxygenated blood to the tissues of the body. Aorta: - The largest artery. It accepts blood from the left ventricle. When the heart contracts (systole) the blood pressure is much higher than when the heart relaxes (diastole). The aorta is very elastic and has an important role in stretching and moderating this pulsatile blood pressure. Arterioles (Resistance Vessels - Because of their high resistance): - These are the vessels where blood pressure drops the most. - They also contain a smooth muscle layer and their diameter is influenced by hormones. Capillaries: - Smallest diameter vessels. Capillary walls are one cell thick, and have fenestra or pores that increase what can diffuse into and out of the capillary. Venules: - Connect capillaries to the veins. Venules and veins take blood back to the heart. Veins (Capacitance Vessels - Because they hold the most blood): - The veins are wider than arteries, which allows them to hold more blood. - The blood pressure is lowest once it has reached the veins. - Veins (and medium-large venules) contain valves. These valves ensure the blood flows in the forwards direction. Because the blood pressure is so low, the veins rely on the skeletal muscle pump and the respiratory pump to have adequate venous return to the heart. When skeletal muscles are functioning (ie: contracting and relaxing), they squeeze the veins. Because of the valves that ensure one-way flow, blood that is squeezed can only move 'forwards', towards the heart; this is the skeletal muscle pump. The respiratory pump is also known as the abdominothoracic pump, because it involves both the abdomen and the thoracic cavity. When a person inspires air the pressure in the abdomen increases, and the pressure in the thoracic cavity decreases. An increase in abdominal pressure compresses any veins in this area, which pushes blood 'forwards'. A decrease in thoracic pressure creates negative pressure, causing the vena cava and the atria to expand, which draws blood in. The venules and veins do have smooth muscle, but it is far less than arteries/arterioles. It is mainly arteries/arterioles that vasoconstrict and vasodilate in response to various hormones that act on blood vessels.

19. Which of the following is involved in the monitoring and control of respiration? A. Monitoring of blood [H+] by central chemoreceptors of the medulla B. Increased production of surfactant by the alveoli in response to rise of blood CO2 C. Signaling from the medulla to the diaphragm to alter the rate and depth of ventilation D. Monitoring of cerebrospinal fluid by peripheral chemoreceptors in the carotid bodies E. Increasing respiratory rate in response to a sharp rise in blood pH 19. Which of the following is involved in the monitoring and control of respiration?
C A: Incorrect. The central chemoreceptors of the medulla monitor [H+] levels in the cerebrospinal fluid. B: Incorrect. The function of pulmonary surfactant is to decrease the surface tension in the alveoli. This makes inspiration less challenging, but production of surfactant is not used as a respiratory control mechanism. C: Correct. The medulla is responsible for control of human respiration, and can signal the diaphragm (and rib muscles) to alter the rate and depth of ventilation in response to signals from the central and peripheral chemoreceptors. D: Incorrect. The peripheral chemoreceptors located in the carotid bodies (and aortic arch) monitor blood levels of [CO2], [O2], and [H+]. E: Incorrect. Respiratory rate would increase in response to a decrease in blood pH. Recall that increased ventilation is the response to respiratory acidosis, which is signaled by a decline in pH.
