Answer:

Carbon fixation during photosynthesis

Explanation:

Photosynthesis is the process through which plants synthesise carbohydrates using light energy from the sun. The overall equation is

CO2 + H20 + (energy) → glucose + oxygen

Photosynthesis can be split into two stages: The light-dependent reactions, and the light-independent reactions. Carbon fixation (sometimes called the Calvin cycle) is part of the light independent reactions

During carbon fixation, carbon dioxide is incorporated into a 5 carbon sugar called RuBP. This immediately forms two molecules of 3-PGA, which is converted into G3P. Some of the G3P is used to synthesise sugars, and the rest is used to regenerate RuBP.

Answer:

Carbon fixation

Explanation:

In this reaction, carbon dioxide reacts with hydrogen ions formed during the light stage to form glucose.This is a complex process involving several enzyme-catalyzed reactions. The process requires energy which is provided by the ATP formed during the light reactions.

What proteins are crucial for creating and maintaining DNA replication forks? Choose the best explanation.

timurjin [86]

Answer:

Explanation:

The correct answer is (B) Helicase creates the replication fork; single-strand binding proteins keep the single strands from reuniting. The replication fork is established by the enzyme DNA helicase, which separates the two complementary strands of a DNA molecule

How can atmospheric nitrogen be converted to ammonium ions or nitrate ions?

Agata [3.3K]

Answer: When a plant or animal dies, or an animal voids waste products, the initial form of nitrogen is organic. Bacteria and fungi in the soil produce enzymes that convert the organic nitrogen back into inorganic ammonium ions (NH4 +). Ammonium is converted to nitrite ions (NO2 -) by soil bacteria like Nitrosomonas

If phosphofructokinase experienced a mutation that interfered with substrate binding, then what other enzyme is going to be most

frozen [14]

Answer: Aldolase

Explanation:

In the metabolism of glucose( glycolysis) phosphofructokinase is an enzyme that catalyzes the conversation of fructose-6-phosphate into fructose-1,6-bisphosphate. This in turn is converted to pyruvate after various steps of enzymatic activity in the glycolytic pathway.

If phosphofructokinase experienced a mutation that interfered with substrate binding, the enzyme that is going to be most immediately impacted in terms of accessing substrate is the ALDOLASE.

Aldolase enzymes cleave fructose-1,6-bisphosphate to triose phosphates( glyceraldehyde 3-phosphate and dihydroxy-acetone phosphate) facilitating an increase in anaerobic production of ATP in muscle.

Therefore, the substrate for binding of aldolase, which is fructose-1,6-bisphosphate is lacking due to mutation of phosphofructokinase enzyme.
