| Question | Answer |
|---|---|
| carotenoids reflect green light | False |
| the ATP synthesized during glycolysis occurs by the process of substrate level phosphorylation | True |
| During aerobic respiration, the formation of ATP occurs in the matrix of the mitochondria | T |
| the 2 major products of the light dependent phases of photosynthesis are NADH and Water | F |
| during the light dependent phase of photosynthesis H+ are moved from the stroma into the lumen of the thylakoids | T |
| nuclear division (M phase) takes longer than DNA replication | F |
| A+G=C+T | T |
| DNA replication in prokaryotes begins at multiple locations around chromosomes, all at the same time | F |
| new DNA is synthesized 5' to 3' and new RNA is 3' to 5' | F |
| RNA polymerase requires a primer to begin transcription | F |
| scientists were convinced that DNA was the genetic material after seeing the results of the exp by Griffith | F |
| the natural and most common form of DNA is A-DNA | F |
| Key regulatory enzyme that we discussed w/ aerobic respiration (located in matrix of mitochondria) | Pyruvate Dehydrogenase |
| approximate size of e. coli chromosome | millions? |
| in Kreb Cycle this 4C molecule picks up 2 of the C from acetyl CoA to then form a 6C molecule. wats the 4C and 6C molecules? | oxaloacetate citrate |
| during photosynthesis energy can be transferred from 1 chlorophyll to anotehr by a process called___ transfer | Inductive Resonance |
| Calvin Cycle occurs in this specific location of chloroplast | stroma |
| this strand located w/in a gene of double stranded DNA has the same sequence of RNA (except there are U's instead of T's in the RNA) | coding strand |
| in yeast, the final product of fermentation is? | CO2 and ethanol |
| in packaging of prokayotic DNA, the closed circular chromosome twists into a? | supercoil |
| histone proteins found in nucleosome | H2A H2B H3 H4 |
| DNA replication is __ b/c the 2 resulting DNA molecules contain 1 original parental strand and 1 new one | semiconservative |
| during translation, the start codon found on the mRNA is? | AUG |
| RNA polymerase II | Transcription -synthesis of mRNA in euk. cells |
| primase | DNA replication -synthesis of RNA primer |
| -10 and -35 | Transcription -2 important regions in promoter region upstream from the start of transcription -help/signals RNA polymerase |
| DNA polymerase I | DNA Replication -removes RNA primer and inserts gaps w/ DNA nucleotides |
| Peptidyl transferase | Translation -removes AA from tRNA in p-site of ribosome and attaches it to AA in A-site |
| rho | Transcription -protein that is used to help in termination of transcription in some pro. cells |
| helicase | DNA Replication -unwinds DNA strands before the replication fork |
| Poly A polymerase | Transcription -adds a "AAAA" tail to the "UUUU" -its a mRNA modification in euk. |
