Vitamin A (also known as retinol) is converted into retinal, an important molecule that can bind to the rhodopsin and capture light (photons). This conversion is done by a retinol dehydrogenase (see figure below). In patients that suffer from night blindness, very low level of retinal are detected. NAD+ NADH + H+ Retinol (Vitamin A) 4. What type of reaction is performed by the retinol dehydrogenase? Retinal A. It is a phosphorylation reaction in which retinol gains a phosphate group B. It is a dephosphorylation reaction in which retinol loses a phosphate group C. It is a redox reaction in which retinol is being oxidized D. It is a redox reaction in which retinol is being reduced E. It is a hydrolysis reaction in which a water molecule breaks down retinol

the reaction catalyzed by glyceradehyde 3-phosphate dehydrigenase is based on NAD+ and a active site cysteine. Also another phosphate group is added. what is the reason for that? a) because one ATP is consumed b) an inorganic phosphate is activated for ATP synthesis C) NADH can be recycld and than converted back to NAD+ for glycolysis d) because one ATP is generated
Corticosteroids (a type of hormone), and Nonsteroidal Anti-inflammatory Drugs (NSAIDs) are non-narcotic pain relievers. Both medications are prescribed to reduce inflammation in the body. NSAIDs such as aspirin, acetaminophen, and ibuprofen are able to reduce pain, fever, and inflammation by blocking the action of the cyclooxygenase enzyme (COX) that catalyzes the conversion of arachidonic acid into prostaglandins. Common corticosteroids include prednisone, cortisone, and methylprednisolone. Choose one of these three corticosteroids. Do some internet research on the corticosteroid that you choose and then explain how the drug works to reduce inflammation.

What is a justification for a hypothesis stating that copper ion is the necessary cofactor in the catechol oxidase reaction? In other words, what evidence based on observation is there to support this claim? Hints: Citric Acid and EDTA bind to copper ions to inhibit cofactor ability. In the catechol oxidase reaction, benzoquinone is produced. What does benzoquinone do in fruits and plants? How does it preserve food? Does citric acid have this same effect?
NADH and succinate are substrates that can be oxidized and will consume oxygen. Rotenone and cyanide are inhibitors of the electron transport chain and can block oxidation. Match each description of the effector to the appropriate oxygen consumption. A plot may match more than one description. Some plots will not match any description. (At least one of the matches in the image was incorrect)
Which of the following statements concerning ATP synthesis is NOT true? a. The open conformation of the ATP synthase is for releasing ATP. b. The gamma subunit in the stalk responds to the flow of H+ and rotates the assembly counterclockwise and thus change the conformations of the active site to synthesize ATP. c. The tight conformation of the ATP synthase is for converting ADP and phosphate to ATP. d. The loose conformation of the ATP synthase is for binding ADP and phosphate. e. Ten protons are required to catalyze the rotation of the subunits so that one ATP is synthesized. Clear my choice

Which of the following statements about the pentose phosphate pathway (PPP) is true? (A) The purpose of the pentose phosphate pathway is to produce NADH for use in anabolic pathways and ribose 6-phosphate for nucleotide synthesis.(B) The oxidative arm of the PPP produces (2) NADPH per glucose 6-phosphate that enters the pathway. (C) Phosphopentose isomerase converts the ribose 5-phosphate made in the oxidative arm of the PPP into ribulose 5-phosphate that is used to form the ribose sugar of nucleotides.(D) The non-oxidative arm of the PPP interconverts between ribose 5-phosphate and a variety of intermediates of b-oxidation. (E) One of the functions of the PPP is to provide NADPH that inhibits glutathione reductase so that it cannot oxidatively damage RBCs.
