Many people who became ill with Covid-19 required oxygen. Some publications in social networks said that you could use apparatus that supplies this gas in fish tanks as a substitute for the oxigen tank. What answer would you give to a person who asks you if is a good a bad idea to do so?

If you examine OX/PHOS in the organism that has the c16 ATP Synthase complex from Q3, how many ATPs will be generated from one Succinate?# of ATPs:

Tissues that are unable to produce nucleotides de novo depend on ____________________ to maintain an adequate supply of adenine nucleotides. (A) the redox reactions carried out by ribonucleotide reductase (B) the action of PRPP amidotransferase(C) uptake of ATP through dietary intake(D) salvaging hypoxanthine using HGPRT (E) the action of xanthine oxidase

In human cells, where does fatty acid elongation (that is, beyond the C16:0 normally produced by fatty acid synthase) occur?   a)On the outer (cytosolic) face of the outer mitochondrial membrane b)On the outer (cytosolic) face of the endoplasmic reticulum membrane c)Free in the cytosol d)In the mitochondrial matrix

Consider a gene in the mitochondrial genome that codes for a channel protein in the inner membrane that allows magnesium ions to travel freely across. If a mutation in that gene resulted in this protein allowing H+ to pass through it rather than magnesium, what would be the consequence for cellular respiration?

Peroxidase is an enzyme found in many organisms, from plant to humans. The function of peroxidase is to break down hydrogen peroxide, which is a toxin produced as a byproduct when oxygen is produced during respiration. Myeloperoxidase is a protein found in neutrophils and catalyzes lipid peroxidation involved in immune defense. The overproduction of myeloperoxidase has been found to function as a mediator for tissue damage in inflammatory diseases. (8 points) a. Identify two examples of environmental factors that may impact myeloperoxidase activity. Describe how each of the environmental factors would affect the reaction rate of the enzyme. b. Predict the how researchers can use myeloperoxidase activity as oxidative stress biomarkers in patients with rheumatoid arthritis. Provide reasoning to justify your prediction.

Which of the following components of the ubiqutin-proteasome pathway are ATPases?  (i.e., which consume ATP in order to function?) (Select all that apply) a)E3 ubiquitin-protein ligase b)19S proteasome c)20S proteasome d)E2 ubiquitin-conjugating enzyme e)E1 ubiquitin-activating enzyme f)Ubiquitin

Glycogen is the major animal storage polysaccharide, and is a polymer of glucose. a) List ALL the biochemical steps involved in storing GLUCOSE as glycogen b) Give NAME/S of the ENZYMES involved in EACH listed step c) What PULLS the reaction forward? d) Give the NAME of the tissue where these steps occur. (HINT: remember glycogen is branched chain).

Describe the process shown in the model below. In addition to your description of the process and the steps involved, identify the following pieces of the model: 1) blue hexagon labeled #1, 2) grey oval labeled #2, 3) the three red ovals. Acetyl COA CYTOSOL MITOCHONDRION 32-34
