The graphic shows the citric acid cycle. A diagram of the citric acid cycle is shown. Acetyl C o A enters the citric acid cycle
vagabundo [1.1K]

Answer:

It enters the citric acid cycle and associates with a 4-carbon molecule, forming citric acid, and then through redox reactions regenerates the 4-carbon molecule.

Explanation:

Acetyl-CoA(2C) associates with oxalacetate(4C) to form citric acid(6C). Then through redox reactions, CO2 molecules result from decarboxylation (COOH becomes R-(R1)CH-R2). And through dehydrogenation H2 molecules are incorporated in NADH+ in FADH2, resulting in the 4-carbon molecule at the beginning (oxalacetate). That's why it's called a cycle(Kreb's cycle or citric acid cycle)

Which hypothesis most likely explains the results at 60°C and 70°C? O A. The substrate has been used up because of the high temp
Leni [432]

Answer: Option B

The enzyme has changed shape because of high temperature.

Explanation:

Enzymes are biological catalysts in living organisms that speed up the rate of chemical reactions.

High temperature changes the shape of enzymes.

Increase or high temperature lead to decrease in enzymes activities. This is due to enzyme protein been denatures by high temperature which is the breaking of molecular bonds within the enzyme protein. When the enzymes bonds are broken, the shape of the enzymes changes and they no longer act as catalysts.
