<h2>Anaphase </h2>

Explanation:

Anaphase includes two major events:

  • Separation of sister chromatids-is due to the destruction of cohesin protein which is catalysed by separase enzyme

Prior to anaphase securin binds to separase and inhibits its activity

The APC with specificity factor cdc 20 targets securin for polyubiquitination which then degraded by proteasome

The released separase becomes active and then breaks the cross link(bridge) between sister chromatids

  • Movement of sister chromatids-occurs towards their respective poles due to shortening of kinetochore microtubules

Which of the following can affect the activity of an enzyme?
Gennadij [26K]
The correct option is 3.
Enzymes are biological catalysts which speed up the rate of biochemical reactions inside the cells. Enzymes are very specific in action and they require specific conditions called optimum conditions for them to function optimally.
When the optimum conditions are not met, an enzyme's activity will be lowered or totally stopped.
Conditions that affect the optimum activity of an enzyme include: temperature, pH level and regulatory activity of regulatory enzymes and hormones.

The conversion of malate to oxaloacetate in the citric acid cycle takes place with the conversion of NAD to NADH. In this reacti
Mariana [72]

Answer:

a) the oxidizing agent.

Explanation:

In the citric acid cycle, malate is dehydrogenated into oxaloacetate and the reaction is catalyzed by malate dehydrogenase. The released electrons are accepted by NAD+. So, NAD+ is reduced into NADH. The substances that accept electrons during chemical reactions and are reduced to oxidize the other substances are called oxidizing agents. NAD+ serves as an oxidizing agent as it accepts electrons to oxidize malate into oxaloacetate.

The various parts of the endomembrane system serve different functions in the cell. in this activity, you will identify the role
DanielleElmas [232]
The endomembrane system is very important for synthesizing, processing, and movement of lipids and proteins in the cell.
The smooth ER function is mainly used for lipid synthesizing and processing, while the rough ER function is for protein synthesizing
