The energy-absorbing molecules for photosynthesis are located in the Thylakoids.
So your answer is A : Thylakoids.
Answer:
Regulatory sites e.g enhancers and silencers
Explanation:
Gene expression involves the synthesis of gene products usually proteins and RNA. However, a certain product might not be needed at all or in small quantity. Gene regulation mechanism is the process that makes this happen. Gene regulation is the mechanism that acts to induce or repress the expression of a gene.
Gene regulation involves controlling the rate and manner of gene expression which is achieved through a set of regulatory proteins called transcription factors. Transcription factors bind to specific regulatory nucleotide sequences and help to turn "on or off" specific genes in the DNA.
Transcription factors can either be ACTIVATORS or REPRESSORS depending on whether they boost or inhibit gene expression. The binding sites for these regulatory proteins called TRANSCRIPTION factors are the regulatory nucleotide sequences on the DNA called enhancers and silencers.
Answer:
The reactions of glycolysis that are shared with those in gluconeogenesis (ie use the same enzymes) are those that Are regulated steps.
Explanation:
Glycolisis and gluconeogenesis are two mechanisms related to the carbohydrates metabolism. Sometimes they are considered reverse processes. However, they are different because of the control points they have where reactions are irreversible.
Glycolisis and gluconeogenesis share 7 common reactions, that are reversible. Thses reactions are coordinated and regulated by F-2 and 6-BP as the answer to the hormonal action.
Glycolisis happens in the muscle, while Gluconeogenesis happens in the liver. Together they form the "Cori Cycle".
Examples of metabolic processes that occur in living organisms are:
- Photosynthesis
- Breaking down of lipids
METABOLISM:
- Metabolism refers to the series of processes that involve the breakdown or build up of molecules to release energy or new products.
- Metabolism can either be catabolic or anabolic depending on how it occurs.
- Anabolism is the build up of large molecules from smaller ones while catabolism is the breakdown of large molecules into smaller ones.
- Example of metabolic processes are photosynthesis, breaking down of lipids.
