Chapter 22 Flashcards
Metabolism consists of?
Catabolism and Anabolism
What is the breaking down of molecules and gives off energy?
Catabolism
What is the building up of molecules and requires energy?
Anabolism
The energy in carbohydrates, lipids, and proteins is used to produce ______ through ________-________ reactions.
ATP, oxidation-reduction
Catabolism produces?
ATP
Anabolism breaks down?
ATP
Glycolysis happens where?
cytoplasm
Kerbs cycle happens where?
mitochondria
electron transport chain happens where?
mitochondria
Glycolysis breaks glucose down into? -with or with o2
with oxygen 2 pyruvic acid
without oxygen lactic acid
What is glycolysis net gain of ATP?
2
What is the end result of glycolysis?
pyruvic acid
What is the Krebs cycle main function?
two remove to electrons.
In the Krebs cycle how many ATP are produced and why?
two, because we have two pyruvic acids
NADH makes how many ATP’s?
3
FADH2 makes how many ATP’s?
2
What produces more energy lipids of carbohydrates?
lipids
B-oxidation is?
lipid metabolism
Acetyl-CoA can be converted into?
ketone bodies (diabetes)
Acetyl-CoA can enter into the krebs cycle and give us?
12 ATP’s (this is b-oxidation)
***What are the three processes occurring in the cell to produce energy in the form of ATP?
glycolysis(occurs in cytoplasm)
krebs cycle (mitochondria)
e-transport chain (mitochondria)
Glucose is the main molecule the cell uses to create?
ATP
What type of compound is glucose?
6 carbon compound
At the end of the electron transport chain oxygen accepts?
electrons
In the herb’s cycle oxygen accepts electrons and forms a bond that is?
H20
Anaerobic respiration makes how many ATP’s?
2
Amino acids are building blocks for what?
Proteins
Glycolysis breaks down into what?
two pyretic acids & also produced are 2 NADH and 2 ATP molecules.
The electron transport chain ends with how many ATP’s?
32 or 34
What is anaerobic respiration?
The breakdown of glucose w/o O2 into two lactic acid and two ATP molecules.
What is aerobic respiration?
The breakdown of glucose with O2 to produce CO2, H2O, and 38 or 36 ATP
Adipose triglycerides are broken down & released as?
free fatty acids.
Free fatty acids is broken down by beta-oxidation what is it end result?
Acetyl-CoA
Glycogenesis is the formation of glycogen from?
Glucose
Lipogenesis is the formation of lipids from?
glucose and amino acids
Glycogenesis is the breakdown of?
glycogen to glucose
Gluconeogenesis is the formation of glucose to form?
amino acids and glycerol
Heat is exchanged through?
radiation, conduction, convection, and evaporation.
What is body temperature regulated by?
a set point in the hypothalamus
