Coupled reactions Study guides, Class notes & Summaries

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 ...

CSEP-CEP Study Guide Theory Exam Questions & Answers 2024/2025 Metabolism - ANSWERSTotal energy expenditure of all cata/anabolic processes (bodies ability to use fuel) Measured by either direct (calorimetry chamber) or indirect (Douglas bag/metabolic cart) calorimetry Calorimetry = measure of energy expenditure (kcals = E to heat 1kg water 1°C) Oxidation-Reduction Reaction - ANSWERS- Are always *coupled reactions* (the energy given off by the exergonic reaction powers the endergon...

ATP - (adenosine triphosphate) main energy source that cells use for most of their work. 1 nucleotide + 3 phosphate group makes it unstable. If loses phosphate group becomes ADP ATP is composed of - ribose (a sugar), adenine (a nitrogenous base), and three phosphate groups Coupled reactions - Energy releasing action usually in the form of ATP breakdown Release of ATP+P causes myosin to change shape and cause muscle movement What do plants and other living organisms need for food - Photosynt...

NR 546 Midterm Exam 2023/2024 Questions AND Answers Update A+ What should the PMHNP consider when prescribing chemical restraints? - Answer-- allergy status -prior med hx for adverse drug reactions r/t the meds ordered in the chemical restraint -state regulations regarding chemical restrains must be reviewed Are the PMHNP and other staff liable if the client has an allergic reaction or adverse side effects to the drugs used for chemical restraint? - Answer-No. The client has been court-...

What are the basic structures of a cell Correct Answer-cell membrane, nucleus, cytoplasm 2 metabolic reactions Correct Answer-anabolism and catabolism What do mitochondria do? Correct Answer-produce ATP what are the two types of chemical reactions Correct Answer-exergonic (give off energy); endergonic (energy required) coupled reaction Correct Answer-a pair of reactions, one exergonic and one endergonic, that are linked together such that the energy produced by the exergonic reaction...
