Catabolic pathways involve the breakdown of complex molecules into simpler ones, releasing energy, while anabolic pathways synthesize complex molecules from simpler ones, requiring energy input. Kinetic energy is the energy of motion, whereas potential energy is stored energy based on an object's position or configuration. Open systems exchange both matter and energy with their surroundings, whereas closed systems exchange only energy. Exergonic reactions release energy and occur spontaneously, while endergonic reactions absorb energy and are non-spontaneous.
What else can I help you with?
Which of the following is an example of a catabolic reaction?
Glycogenolysis
Which of the following is true for all exergonic reactions?
the reactants have more total energy than the products.
Which of the following statements about the role of ATP in cell metabolism is true?
The energy from the hydrolysis of ATP may be directly coupled to endergonic processes by the transfer of the phosphate group to another molecule. A key feature in the way cells manage their energy resources to do this work is energy coupling, the use of an exergonic process to drive an endergonic one. ATP is responsible for mediating most energy coupling in cells, and in most cases it acts as the immediate source of energy that powers cellular work.
Ask us anythingWhich of the following describes a nonspontaneous reaction?
a non spontaneous reaction is a reaction that doesnt occur naturally and it normally tends to favor the reactants of a chemical reaction. Another thing is that it doesnt really produce free energy
Which of the following cells in the eye helps us to distinguish colourrods?
rods orcones
what are the following processes releases energy to be used by a cell?
Chemical reactions that release energy are called exergonic. Cellular processes that release energy are called catabolic, or catabolism. {I remember this by thinking 'What does a cat do with its claws to your furniture - it breaks things down.' Also, anabolic steroids are for 'building up'.} The main energy producing catabolic reactions occur using Respiration that releases usable biochemical energy in the form of Atp.
Which one of the following tests will best allow you to distinguish between an aldehyde and an alkene?
bromine water
How would you distinguish between the following pair of compounds using IR spectoscopy(benzyl alcohol and p-cresol)?
Absorption spectra are different.
Distinguish between the concept of the short run and long run period theory of the firm?
Explain which of the following would be considered the long-run and short-run and why.
Which of the following gives an easy way to distinguish a metal element from a non-metal element?
Metals are listed on the “left hand side” of the periodic table, while non-metals are on the “right hand side
What is demotic writing?
Demotic refers to either the ancient Egyptian script derived from northern forms of hieratic used in the Delta, or the stage of the Egyptian language following Late Egyptian and preceding Coptic. The term was first used by the Greek historian Herodotus to distinguish it from hieratic and hieroglyphic scripts. By convention, the word "Demotic" is capitalized in order to distinguish it from demotic Greek.
How can you distinguish a real royal doulton Toby jug from a fake?
