Exam 3 Review Q's Flashcards
Produced from lipolysis of triglycerides
Glycerol and fatty acids
Most abundant product of the rxns of Krebs cycle
NADH (6)
Where each process of cellular respiration occurs
- Glycolysis: cytosol
- Formation of acetyl-CoA: mitochondria
- Krebs cycle: mitochondria
- ETC: inner membrane of mitochondria
Final electron acceptor in ETC
O2
Gluconeogenesis
Synthesis of new glucose from noncarbohydrate precursors; occurs in liver and kidneys
Glycogenesis
Storing glucogen; occurs in liver and muscle cells
Glycogenolysis
Breakdown of stored glycogen; occurs in hepatocytes and the myocytes
Source of most cholesterol in body
LDL’s and hepatocytes
Order of filtrate flow in nephron
- Glomerular (Bowman’s) capsule
- Proximal convoluted tubule
- Descending limb of the loop of Henle
- Thin ascending limb of the loop of Henle
- Thick ascending limb of loop of Henle
- Distal convoluted tubule
Carries urine from kidney to urinary bladder
Ureter
Return of substances to the blood from filtrate in kidneys
Tubular reabsorption
Part of renal tubule impermeable to water
Ascending limb
What renal corpuscle consists of
Glomerulus and glomerular (Bowman’s) capsule
Why countercurrent exchange is important in functioning of kidneys
Enables formation of concentrated urine
Most abundant ion in extracellular fluid
Sodium
Most abundant ion in intracellular fluid
Potassium
Main protein buffer in blood
Hemoglobin
Percent of extracellular fluid in body is interstitial
80%
How kidneys help control pH of body fluids
Allow for pH adjustments
- H ions and bicarbonate ions can be reabsorbed into blood/secreted into filtrate as needed for pH adjustment
Main hormone secreted by developing ovarian follicles
???
Functions of LH
Stimulates cells in testes to produce testosterone
What sperm fuses with during fertilization
Oocyte
Direct effect of the inhibition of release of GnRH from hypothalamus
Testes will not grow at puberty and they will not produce their own testosterone and sperm
Diploid cells produced by an embryonic germ cell
Spermatogonia
What happens to corpus luteum at end of ovarian cycle if female isn’t pregnant
Will break down
Transport protein
Hemoglobin
Key molecule at metabolic crossroads
- Pyruvic acid
- Acetyl CoA
- Glucose-6-phosphate
2 coenzymes that are used in redox rxns of aerobic respiration
FAD and NAD
Structure of nephron that reabsorbs the most substances
PCT
Nitrogenous waste products of humans
Urea
Hormone released when blood volume and BP increase
ANP
Thirst center of brain
Hypothalamus
Main protein buffer in blood
Hemoglobin
Greatest amount of water loss from body from this
Urination i think
