what is in between two amino acid/proteins?
amino acids are linked by?
peptide bonds
what is the secondary structure of amino acids
- aa shaped by hydrogen bond
- alpha helices and beta pleated sheets
What is not in DNA bases? that is used in RNA
uracil
what is ketosis
increased blood ketones
what is the basis/building blocks of nucleic acids?
nucleotides
what is prostaglandin
cyclic carbon with fat chains
rate of diffusion does not include?
ATP
The resting membrane potential is -70mV, Na+ is 65 mV. Na+ contributes more than K+…
False
What is the non-coding region in genes in pre-mRNA
introns
Growth by increase in number of cells
hyperplasia
Transamination/deamination can be converted to by…acetyl coa
all of the above?
krebs yes, pyruvic acid yes
what will inhibity glycolysis
excess of ATP
What is Na+/K+ pump
- 3 Na+ out and 2 K+ in
- primary active transport
What does secondary transport often uses?
symport
Secondary active transport uses energy from
uses energy from downhill movement of Na+ to drive “uphill” movement of another molecule
What does glycolysis uses and end product
uses glucoses with end product of water
what is telomeres
the non coding of genes in end of chromosomes end cap
when does sister chormatids separate
anaphase
What is trapped inside cell/charge?
anions
Positive feedback loop does what?
amplifies initial change
Homeostasis does what
maintain constant internal condition
