How much ATP is produced in 5 molecules of glucose in the presence of oxygen in an obligate aerobe?
Answer:
190 ATP molecules
Explanation:
Cellular respiration is the process whereby energy (ATP) is obtained in the cells of living organisms by breaking down glucose molecules. Cellular respiration can either be aerobic or anaerobic depending on whether oxygen is present or not.
In the presence of oxygen, aerobic respiration, which consists of three stages namely: glycolysis, Krebs cycle and oxidative phosphorylation, is employed. Per glucose molecule;
- Glycolysis produces 2 ATP molecules,
- Krebs cycle produces 2 ATP molecules
- Oxidative phosphorylation produces 34 ATP molecules
Hence, in total, 38 ATP molecules is produced per glucose molecule in aerobic respiration. According to the question, 5 molecules of glucose will yield 5 × 38 = 190 molecules of ATP.

What happens in an endothermic reaction?
Answer:
In endothermic reactions, more energy is absorbed when the bonds in the reactants are broken than is released when new bonds are formed in the products. Endothermic reactions are accompanied by a decrease in temperature of the reaction mixture.
What would happen if a cell couldn't make catalase?
Answer:
If hydrogen peroxide is not broken down by catalase, additional reactions convert it into compounds called reactive oxygen species that can damage DNA, proteins, and cell membranes. ... A shortage of this enzyme can allow hydrogen peroxide to build up to toxic levels in certain cells
If hydrogen peroxide is not broken down by catalase, it can be converted into reactive oxygen species, which can damage DNA, proteins, and cell membranes.
What is catalase?Catalase is an important enzyme that uses hydrogen peroxide, a non-radical ROS, as a substrate.This enzyme breaks down and neutralizes hydrogen peroxide to maintain optimal molecular levels within cells.It is also essential for cell signaling processes. The catalase enzyme breaks down hydrogen peroxide (H2O2) into water and molecular oxygen, protecting cells from oxidative damage by reactive oxygen species.Commercially available catalase is produced from Aspergillus niger by a solid-state fermentation process.Peroxidase or catalase is an enzyme of the oxidoreductase class. The peroxidase enzyme catalyzes the breakdown of hydrogen peroxide into water and molecular oxygen as shown.Catalase is a tetrameric heme protein that detoxifies H2O2 into oxygen and water.It is a metalloprotein oxidoreductase and when present in high concentrations he efficiently removes H2O2.To learn more about catalase, refer

What did scientists believe was contributing to the depletion of the ozone layer and why?
CFCs and other halogen-source chemicals in the stratosphere were discovered to deplete the ozone layer.
What is ozone layer depletion?
Ozone depletion is the steady lowering of the Earth's ozone layer in the high atmosphere, which is produced by the discharge of chemical compounds from industry and other human activities that contain gaseous chlorine or bromine.
The ozone layer acts as a buffer against the sun's potentially dangerous ultraviolet rays. The destruction of the ozone layer puts humans in direct contact with dangerous ultraviolet rays, which can lead to a variety of health problems including cancer, cataracts, skin illnesses, and a weakened immune system.

On Isle Royale, wolves are the main predators of moose. The graph shows the changing wolf and moose populations on the island over a 50-year time span.
The graph plots the populations of moose and wolves in separate lines from 1955 to 2005. The two populations appear to follow opposite trends: when one population is higher, the other population is lower.
Which statement provides the strongest explanation for the trends in the two populations?
A. The populations of predators and prey are limited by abiotic factors only.
B. Predation acts a density-dependent limiting factor on prey, but not on predators.
C. Predation acts as a density-independent limiting factor on predators, but not on prey.
D. Predator-prey relationships act as density-dependent limiting factors on both predators and prey.
Answer:
D
Explanation:
The statement provides the strongest explanation for the trends in the two populations is predator-prey relationships act as density-dependent limiting factors on both predators and prey. Hence option D is correct.
What is predator?Predator is defined as an organism that mostly hunts and consumes other organisms for food. The term "predator" refers to a species that hunts and eats specific other organisms. The animals that predators consume are referred to as prey.
Predator-prey interactions and prey-predator interactions are both crucial density-dependent population controls. The other population's size determines how each population changes in size. When the population density reaches a particular point, a density-dependent limiting factor takes effect. Competition, parasitism, and disease are other instances of density-dependent limiting variables.
Thus, the statement provides the strongest explanation for the trends in the two populations is predator-prey relationships act as density-dependent limiting factors on both predators and prey. Hence option D is correct.

Answer:
d. Pluripotency markers
Explanation:
Pluripotency can be defined as the capacity of individual cells to differentiate into any cell type. Pluripotent transcription factors are pluripotent proteins that promote the differentiation of embryonic stem cells (ESCs) into stem/progenitor cells by inducing the expression of target genes, which are also capable of maintaining their pluripotent state. For example, SOX2, OCT4 and NANOG are pluripotent transcription factors highly expressed in ESCs in order to maintain the pluripotent state of these cells.
A student is investigating how substrate concentration affects the rate of anenzyme-catalyzed reaction. Which threevariables should be kept constant in the setup of thestudent’s investigation? Select all three variablesA. temperature of the reactionB. amount of enzymeC. amount of substrateD. amount of productE. pH of the reaction
Answer:
A. temperature of the reaction
B. amount of enzyme
E. pH of the reaction
Explanation:
Temperature should be kept constant because enzymes operate at different activity rates depending on the temperature. The same goes for the pH as well with different enzymes having different optimal pH levels.
The amount of enzyme should be kept constant as well because different concentrations of enzymes can determine how fast the reaction will occur.
Essentially anything that could affect enzyme activity apart from substrate concentration should be kept constant.
