All the different biomolecules can serve as energy sources. Explain which biomolecules are catabolized in which reactions.
Carbohydrates are catabolized by glycolysis, TCA cycle, and energy is produced by oxidative phosphorylation.
Lipids are catabolized by beta-oxidation.
Proteins are catabolized by Proteases. The amino acids produced by the catabolism are converted into various metabolites that feed into the TCA cycle to generate energy.
All the different biomolecules can serve as energy sources. Explain which biomolecules are catabolized in which...

Question 1 2.5 pts Some reactions serve to break down molecules (like glucose) to release energy that is stored in them. These types of reactions are (1). Other reactions have the opposite role and serve to build larger molecules. These types of reactions require energy input and are (2). The "batteries of the cell are used to transfer this energy between the two types of reactions above. The fully charged version of the battery that can be used to power...
Economies of scale can arise from many different sources." Explain the above sentence explaining what is meant by the "economies of scale" and the different sources that allow firms to have the economies of scale. Give examples.
Describe the influence of exercise on energy generation. Explain the different factors that can be influenced by exercise. Make sure to include all aspects of energy generation including the different macronutrients that are involved in energy generation.
Which condition can lead to two populations becoming different species? all of these A barrier to gene flow exists between the two populations. Individuals in the two populations have significant genetic differences from one another. Individuals may live in geographically isolated areas. Individuals in the two populations mate at different times. Which of these is NOT an example of adaptive evolution? bottleneck all of these gene flow founder effect Mutation Which of these does NOT influence allele frequencies in a...
