Question 1: 2 parts of digestive system

Answer:

alimentary and accessory

Question 2: protein structure

Answer:

primary (beads), secondary (twist), tetiary, quaternary

Question 3: 4 components of blood

Answer:

-plasma (55%), RBC, WBC, platelets -avg adult has 4-5 quarts

Question 4: phospholipids

Answer:

• fatty acid chains, glycerol, phosphate group

Question 5: cell resp. step 1 (glycolysis)

Answer:

-new molecule is formed Acetyl-coA molecule entrers cycle and binds to oxalaocetate (creating a 6 carbon molecule)

Question 6: vascular system

Answer:

(high pressure) arteries, arterioles, capillaries, venules, veins (low pressure)

Question 7: types of lipids

Answer:

saturated, unsaturated, trans fatty acid: hydrogeneration

Question 8: lipids

Answer:

are hydrophobic, chains/rings of hydrocarbon

Question 9: Elements of biology

Answer:

Carbon (backbone), Oxygen, Hydrogen, Nitrogen

Question 10: components of circulation

Answer:

central pump, vascular system, circulating fluid

Question 11: C4 photosynthesis

Answer:

-water loss minimized in warm climates -requires more energy

Question 12: right heart

Answer:

right atria, right ventricle, pulmonary cicuit

Question 13: Proteins

Answer:

long chains of 20 amino acids. functions: structure, enzymes, body functions

Question 14: Photosynthesis

Answer:

process by which some organisms capture energy from the sun to create sugar

water + CO2 = O2 + sugar

Question 15: calvin cycle

Answer:

use ATP & NADPH, plus enzyme rubisco (CO2 sticky tape) and other chemicals floating around in calvin cycle to make sugar

Question 16: CAM photosynthesis

Answer:

-water loss minimized in hot climates -requires more energy -slow growth

Question 17: 3 parts of nucleic acids

Answer:

sugar,phosphate, nitrogen base

Question 18: Alimentary canal

Answer:

moth, esophagus, stomach, small intestine, large intestine/ colon

Question 19: photosynthesis step 3

Answer:

photosystem 2 (more excited electrons) sent to another electron transport chain

Question 20: ADP (adenosine diphosphate)

Answer:

energy released as a phosphate group ejected from ATP

Question 21: triglycerides

Answer:

• fatty acid chains and glycerol, storage reserves

Question 22: cell resp. step 3 (kreb cycle)

Answer:

-oxacoacetate is reformes, ATP is generated, and more high energy electron carriers are formed -produce NADH and FADH2 -2 turns of cycle are necessary to compute

Question 23: cell resp. step 2 (prep for kreb cycle)

Answer:

-high energy electron carriers (NADH) are made and CO2 is exhaled

• 6 carbon molecules donate electrons creating NADH (2 CO2 molecules are released into atmosphere)

Question 24: carbohydrates

Answer:

used to store and release energy, break down into sugars (monosaccharides- glucose, disaccharides, polysaccharides)

Question 25: cell resp. step 4 (Electron transport chain)

Answer:

-electron from FADH2 or NADH jump from inner mitochondrial membrane to tube until it finds O2 -with addition of hydrogen ions -when enough H+ are on one side of inner mitochondrial membrane, they rush to other side of membrane, releasing energy = about

Question 26: Accessory structures

Answer:

salvary glands, liver, gallbladder, pancreas
