Catabolic reactions - Study guides, Class notes & Summaries

What is the definition of homeostasis? What are some examples of processes that are regulated to maintain homeostasis? Correct Answer-Ability to maintain relatively stable internal conditions even though the outside world changes continuously What is the difference between "homeostasis" and "steady state"? Correct Answer-Steady state is a variable that is unchanging but not necessarily a "normal" resting rate What are the two types of metabolic reactions? One builds and one breaks. C...

bioenergetics Ans: the flow of energy in a biological system; the conversion of macronutrients into biologically usable forms of energy catabolism Ans: the breakdown of large molecules into smaller molecules catabolism Ans: associated with the release of energy anabolism Ans: synthesis of larger molecules from smaller ones exergonic reaction Ans: energy-releasing reactions that are generally catabolic endergonic reaction Ans: require energy and include anabolic processes and the con...

Chapter 2 - ️️ᕦ(ò_óˇ)ᕤ Factors that regulate enzyme activity: - ️️- temperature - pH - substrate concentration - product inhibition - cofactors (cAMP, AMP, calcium, etc. can either activate or inhibit enzyme activity) Gain of a control system - ️️Degree to which a control system maintains homeostasis; a system with an appropriate gain is more capable of maintaining homeostasis than a system w/ low gain Simple biological control system components - ️️- stimulus - ...

active site (biochemistry) - the region of an enzyme that binds to a protein or to another substance during a reaction, where catalytic activity occurs allosteric site (biochemistry) - site at which a small regulatory molecule interacts with an enzyme to inhibit or active that specific enzyme, binding of allosteric effector is in general noncovalent and reversible amino acid (biochemistry / molecular genetics) - a simple organic compound containing a carboxyl group and an amino group am...

UCI Bio 93 Midterm 2 Questions and Answers 100% Pass What is a metabolic pathway? A pathway that a molecule goes through, resulting in a specific product. What is metabolism? The totality of an organisms chemical reactions Gibbs free energy Portion of a system that can perform work when temp and pressure are uniform throughout the system. What does a negative Delta G mean? A process that is spontaneous/exergonic What does spontaneous mean? Means that a process will occur. ...

What is the basic structure of a cell? Correct Answer- What are the two types of metabolic reactions? One builds and one break. Correct Answer-Anabolic is the synthesis and building Catabolic is the breakdown of molecules What do mitochondria do? Correct Answer-Takes energy sources (Carbohydrates and fatty acid) Makes Heat (Not 100% efficient and wasted energy) ATP (Energy homeostasis) Cell signaling (Intracrine) What are the two types of chemical reactions? Correct Answer-NAD FAD ...

Biology 1001 MUN: Section 5 Latest Version Graded A+ **1. What does metabolism encompass?** - Metabolism includes all the chemical reactions that sustain life within an organism. **2. What are anabolic pathways?** - These are chemical reactions that consume energy to construct larger molecules, storing energy in the process. **3. Describe catabolic pathways.** - These pathways break down complex molecules into simpler ones, releasing stored energy to perform cellular work. ...
