Which processes release energy: anabolic or catabolic processes? Do catabolic or anabolic reactions give us ATP? What molecule is formed as a result of catabolic processes? What does catabolic mean in biology? Are all catabolic reactions exergonic?
Activation energy is the energy required to start a chemical reaction. Some reactions proceed immediately when the reactants are brought together, but for many others, placing the reactants in close proximity is not enough. An external energy source to s
What does "enzyme selectivity" mean? What is the substance an enzyme affects? How do enzymes affect activation energy? How is enzyme activity regulated by the cell? How does an enzyme work? What is the region of an enzyme that binds the substrate?
Lifestyle interventions (including diet, exercise and behavioural changes) are the cornerstone of obesity management with diverse benefits, but even the most intensive lifestyle interventions result in up to 10% mean weight loss (WL) and weight maintenance remains a challenge, as 80% of WL is ex...
Relative relevance is the mean relevance of pixels belonging to the object (ball, paddle, tunnel) divided by the mean relevance of all pixels in the frame. Thin lines: six training runs. Thick line: average over the six runs Full size image While feature selection has traditionally explained ...
The preparation of a target organic compound can be mapped using retrosynthetic analysis. In a retrosynthesis, the bonds in the target organic compound are disconnected to give plausible intermediates or initial reactants that can be obtained from commercially availab...
Action requires a sort of personal activation energy to overcome inertia, but it also requires connection to a community of others who share similar moral goals and who can reinforce your conviction, improve your thinking, and give you operational scale when needed. Some of these communities exist...
Uh oh, a “why?” question in biology! There are many potential, and not mutually exclusive, answers to such questions. Ultimately there is a historical, evolutionary answer that underpins it all (“ostriches evolved two kneecaps because…”). But we like ostrich knees and their funky double...
Explain how an enzyme lowers the required energy of activation for a reaction. How does substrate concentration affect enzyme activity? (a) What is the function of a restriction enzyme? (b) How are they different from nucleases? What does it mean to say that an enzyme-catalyzed reaction is ...
What does "enzyme selectivity" mean? Define enzyme denaturation in terms of protein structure. What environmental factors can denature enzymes? Which statement about enzyme catalyzed reactions is NOT true? a. Enzymes from complexes with their substrates. b. En...
