Answer:
Glucose metabolism is impeded as the conversion of fructose-6-phosphate to fructose-2,6-bisphosphate in glycolysis is impossible after a knockout in mice.
On glucose levels, glucose levels rise as the feedback mechanism set in place to control the metabolism of glucose to ATP is absent.
Explanation:
GLUCOSE METABOLISM
PFK-2/FBPase-2 is an enzyme involved in regulating glycolysis and gluconeogenesis. It is found abundantly in organs such as the liver and heart.
It is a rate limiting enzyme critical in the catabolism of glucose which produces energy in the body.
Phosphofructokinase-2 (PFK2) catalyzes the conversion of fructose-6-phosphate to fructose-2,6-bisphosphate. PFK-2 is regulated by glucagon in the liver, epinephrine in muscle and by insulin, glucagon and epinephrine being hormones.
A knockout in mice, will conversely lead to an increased level of fructose-6-phosphate in glycolysis and with a lack of the rate limiting enzyme, glucose levels rise, leading to a consequential rise in glucose levels.
The rate limiting enzyme functions in the body's natural feedback mechanism to regulate the production of energy as well as the release of glucose for the production of energy.
The ribosome has two subunits; a smaller one and a bigger one. The smaller one contains 21 proteins and one rRNA molecule, and the larger subunit contains 34 proteins and two rRNA molecules. Ribosomes are found in prokaryotes and eukaryotes (although they are a little different, they have the same function). Ribosomes are made of nucleolus. Some people might think that mRNA also helps to form the structure of the ribosome, but this is not the case. rRNA makes up the ribosome of a cell, while mRNA travels to the ribosome of a cell during protein synthesis in order to code for the amino acids. Only during protein synthesis will the mRNA appear in a ribosome. mRNA does not make up the structure of the ribosome! Hope this helps! RNA and proteins
Answer:
Photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.
Explanation:
Abiotic factors are non-living physical environmental factors that affect living organisms and the ecosystem. These factors include temperature, humidity, rainfall, sunlight among others, they affect the way living things thrive and adapt to an ecosystem. Biomes are communities of plant and animals with similar characteristics in an environment they thrive in. Rainfall and temperature are the abiotic factors that exert greatest influence in the Biome classification.
