25
Bundle of HIS
Pass impulse (from avn) to PURKINES fibre
26
Smaller fibres in heart
PURKINES | controls contraction if ventricles
27
Bicuspid
Left
28
Tricuspid
Right
29
Systole
Contract
30
Diastole
Relax
31
Cilia is made from...
Protein
32
Ribosomes are made from...
Protein, 2 subunits
33
How many chromosomes does a normal cell have
23 pairs or 46 single chromosomes
34
Prophase I consists of 5 phases...
``` LEPTOTENE ZYGOTENE PACHYTENE DIPLOTENE DIAKINESIS ``` 90% of meiosis cycle
35
Leptotene
LEPTOTENE Chromosomes - thin threads -each = sister chromatids Total : 46 chromosomes
36
Zygotene
ZYGOTENE | Synapsis : Homologous chromosome comes close together to form pairs
37
Pachytene
PACHYTENE * Pairing is complete * • ‘Tetrad chromosome’ formed (four sister chromatids) aka ‘Bivalent’ (two chromosomes) CHIASMATA formed (link between non sister chromatids) from crossing over •Recombination/crossing over(non sister chromatids exchange segments)
38
Crossing over/recombination
Exchange of segments of non sister chromatids Cause of genetic variation Produce chiasmata
39
Link from crossing over called?
Chiasmata
40
S phase
Dna duplication Cetrioles too!!
41
Homologous chromosome
Have genes that control the same traits | Dna does /control the same function
42
Diplotene
Homologous chromosomes uncoils REMAINS IN BIVALENT STRUCTURE still attached at chiasmata
43
Diakinesis
Chromosome condenses even more Nuclear envelops breaks down Nucleoli disappears Mitotic apparatus starts to form
44
Centromere
Attaches two sister chromatids
45
Centrosome
Produce mitotic spindles at poles
46
Kinetochores
On centromere where mitotic spindles attach to
47
Metaphase I
Centrosome migrate to equator BIVALENT ATTACHMENT Attach spindles to kinetochores and entire bivalent, not just individual chromosome Line up bivalent structure at equator (metaphase playe)
48
Anaphase I
Short + pulls bivalent structure towards poles Chiasmata breaks Sister chromatids not separated Cell elongates for divison
49
Telophase I
Mitotic apparatus disappear New membranE Each daughter cell = 23 chromosome - two sister chromatids each) Haploid because diploid parents
50
Cytokinesis
Cleavage furrow (animal cells)
51
When homologous chromosomes successfully separates ir fails to separate in meiosis
Disjunction (successful) Non-disjunction (fails) Eg down syndrome TRISOMY of chromosome 21
52
Sebum
Secreted from swear glands | Helps prevent cracks in skin
53
Apoplast vs symplast
``` Apoplast = cellwall Symplast = cytoplasm ```
54
AT CG No. Of H bonds
AT 2 | CG 3
55
Which of these does not involve the brain?? Homeostasis Temp regulation Osmoregulation Blood glucose regulation
Glucose (Pancreas secretes insulin/glucagon Effects liver) Other two - hypothalamus
56
Anaerobic respiration equation
Glucose >> ethanol + co2 | Glucose >> lactic acid
57
How does 1 plants 2 animals 3 bacteria Store glucose??
1 starch | 2,3 glycogen
58
Gene expression is controlled during...
Transcription
59
Impulse rates are affected by...
Myelin sheath + diameter of axon
60
What organelles in animal cells contain rna
Ribosome
61
Recombinant plasmid
Plasmid ที่ใส่ desired gene เข้าไปแล้ว
62
Nervouse control of heart rate (brain name)
Brain stem
63
Anabolic | Catabolic
Ana - build | Cata ~ breaks down
64
Prokaryote vs eukaryote dna
``` P = circular E= linear ``` Both double stranded
65
Anticodons vs codons
``` Anti = trna Codon = mrna ```
66
Ribosomes size
70s in bacterial 80s in eukaryote Exception - mitochondria + chloroplast (70s)
67
Humoral
Antibodies
68
Toxoids
Modified toxins
69
Weakened pathogens for vaccines
Attenuated By chemicals, cultured in high temp
70
Chemicals added to vaccines to increase effect
Adjuvants
71
Granna | Stroma
``` Granna = photosynthesis Stroma = fluid surrounding granna ``` NADP+ is reduced
72
Plant cells with chloroplast
Palisade mesophyll Spongy (a little) Guard cells
73
Lock,Key
Substrate key | Enzyme lock
74
Colon
Large intestine
75
Xylem,Phloem
Xylem- water + mineral ions | Phloem - sucrose + amino acid
76
Lactic acid
C3H6O6
