Chapter 5 -4 Flashcards
What is the most common type of control?
Feedback inhibition (negative feedback)
What do regulatory molecules do?
control allosteric site
Types of regulatory molecules are?
Activators
Inhibitors
The end product of metabolic pathway acts as?
an inhibitor
What do pesticides do?
inhibit key enzymes in the nervous system
What do antibiotics do?
inhibits enzymes that are essential to bacteria
What kind of pathway does cellular respiration have?
catabolic/exergonic
What kind of pathway does photosynthesis have?
anabolic/endergonic
Cellular respiration & photosynthesis both manage energy by?
electron transfer: Redox Rxn’s
using coenzymes
What are Redox Reactions?
great energy (electron) conveyors mvmt of electrons by electronegative molecules
What is oxidation?
loss of electrons and hydrogen ions
What is reduction?
gain of electrons and hydrogen ions
How do a series of Redox Rxn’s manage energy release?
by stepping down electron transfer: falling
What happens in redox reactions in cellular respiration?
enzymes transfer the electrons/ H+’s to intermediate electron carriers
