Concept
Metabolism
Metabolism is the network of chemical reactions that extract energy and build or break down molecules in living systems.
Metabolic regulation connects molecular networks to organismal energy and disease biology.
Evidence
What the evidence shows
Drawn from 8 studies in this library. Each claim links to the studies behind it.
Multiple empirical papers in this library examine metabolism with mechanistic biological findings.
Highly complete genome assembly; wild species retains tolerance traits diluted by domestication for yield; useful for breeding stress-tolerant alfalfa.
~43k CDS per tissue with extensive annotation tied to secondary-metabolite pathways.
ZFP36 family members are acute growth-factor immediate-early genes; they bind many metabolic mRNAs and promote Eno2 mRNA decay; loss elevates ENO2/PEP and alters the metabolome; regulation appears in neonatal retinal angiogenesis.
MEP pathway contributes to ginsenoside biosynthesis; IspD predicted as a key MEP enzyme; tissue patterns match ginsenoside distribution.
Open questions
Where studies disagree
Open questions, not settled findings — worth knowing before you cite any one of these.
Systems and scales differ across metabolism studies (species, tissues, methods), so mechanisms should not be over-generalised.
Common misconceptions
Metabolism findings from one model organism always transfer to humans.
Model systems teach mechanism; transfer to other species is a separate empirical claim.
Exam-style questions
Short-answer questions that ask you to explain or compare, not recall.
What is Metabolism?
Metabolism is the network of chemical reactions that extract energy and build or break down molecules in living systems.
Why does Metabolism matter for biology undergraduates?
Metabolic regulation connects molecular networks to organismal energy and disease biology.
The studies
- What extreme physiologies does the painted turtle genome encode?
The western painted turtle genome informs evolution of extreme anoxia and freeze tolerance in a slowly evolving vertebrate lineage.
- What can a wild Medicago genome teach about stress tolerance?
A highly complete Medicago ruthenica genome provides genetic resources for environmental-stress tolerance missing from yield-focused cultivated alfalfa.
- How does ZFP36 reshape metabolism after growth signals?
Growth factors induce ZFP36, which binds and decays metabolic enzyme/transporter mRNAs—especially Eno2—tuning glycolytic metabolism.
- Does the MEP pathway feed ginsenoside production?
Transcriptomics implicates the chloroplastic MEP pathway—highlighting IspD—in ginsenoside biosynthesis beyond the classic MVA route.
- Salmon fat-cell differentiation transcriptome
Atlantic salmon adipose SVF cells progress through proliferative then adipogenic expression programs.
- Folliculin tunes mTORC1 toward TFE3
FLCN–RagC signaling makes mTORC1 substrate-selective for TFE3 phosphorylation under amino-acid cues.
- How do Cryptosporidium oocysts survive outside hosts?
Oocyst transcriptomes reveal metabolic features that help Cryptosporidium parvum endure environmental stresses without nutrient supply.
- Aloe vera medicinal pathway transcriptome
De novo root and leaf transcriptomes highlight saponin and anthraquinone metabolism genes.
