(a)
Interpretation:
Electron transport chain occurs within mitochondria of a cell or in a cell’s cytosol has to be indicated.
Concept introduction:
Electron transfer chain is defined as a series of biochemical reactions in which the electrons and hydrogen ions obtained from NADH and FADH2 react with molecular oxygen to produce water. NADH and FADH2 are oxidized through
(b)
Interpretation:
Lipogenesis occurs within mitochondria of a cell or in a cell’s cytosol has to be indicated.
Concept introduction:
Lipogenesis is the process employed for the synthesis of fatty acid. The starting precursor for the synthesis is acetyl CoA. The enzyme employed for the process is fatty acid synthase. It is a multienzyme complex that ties the reaction responsible for the synthesis of fatty acid. This process is the reverse of the degradation of fatty acid.
(c)
Interpretation:
Glycerol
Concept introduction:
Triacylglycerol mobilization is an ongoing process in which triacylglycerols that are stored in the adipose tissue are hydrolyzed. Fatty acids and glycerol are the products of triacylglycerol mobilization. The products are released into the bloodstream.
After entering the bloodstream, the glycerol travels to the kidneys or liver. The first stage of glycerol metabolism occurs in the liver or kidney where it is converted to
(d)
Interpretation:
Gluconeogenesis occurs within mitochondria of a cell or in a cell’s cytosol has to be indicated.
Concept introduction:
Gluconeogenesis is an eleven-step pathway in which glucose is produced from non-carbohydrate substances. The net overall equation for gluconeogenesis is as follows:

CI Brarrow_forwardох 4-tert-butyl oxy cyclohex-1-ene Incorrect, 1 attempt remaining The systematic name of this compound classifies the -OR group as a substituent of the hydrocarbon, which is considered the principal functional group. The ether substituent is named with the suffix 'oxy'. The general format for the systematic name of a hydrocarbon is: [prefix/substituent] + [parent] + [functional group suffix] Substituents are listed in alphabetical order. Molecules with a chiral center will indicate the absolute configuration at the beginning of its name with the R and S notation.arrow_forward5. Compressibility (6 points total). The isothermal compressibility is a measure of how hard/easy it is to compress an object (how squishy is it?) at constant temperature. It is др defined as Br=-()=-(200²)T' (a) You might wonder why there is a negative sign in this formula. What does it mean when this quantity is positive and what does it mean when this quantity is negative? (b) Derive the formula for the isothermal compressibility of an ideal gas (it is very simple!) (c) Explain under what conditions for the ideal gas the compressibility is higher or lower, and why that makes sense.arrow_forward
