What enzyme catalyzes the reaction in the Calvin cycle?

Mashcka [7]

Answer:

ribulose bisphosphate carboxylase (RuBisCO)

Explanation:

The Calvin cycle is a process utilized to ensure carbon dioxide fixation. ... The carbon dioxide is combined with ribulose 1,5-bisphosphate to form two 3-phosphoglycerate molecules (3-PG). The enzyme that catalyzes this specific reaction is ribulose bisphosphate carboxylase (RuBisCO).

Hydrogen is the simplest element it has an atomic number of 1. There are three hydrogen isotopes: H1, H2, and H3. Explain how th

Archy [21]

All isotopes of hydrogen will always contain one proton, as a change in the amount of protons will change the substance. Assuming all isotopes aren’t ions and therefore don’t have a charge, then each of these isotopes has one electron. The only difference between them is the amount of neutrons to account for the different atomic masses.

H1
one proton
one electron
zero neutrons

H2
one proton
one electron
one neutron

H3
one proton

You have a 16N sack of potatoes that you need to lift onto the kitchen counter. You set up a pulley system with a mechanical adv

natali 33 [55]

A force of 8 N will be required.

<h3><u>Explanation:</u></h3>

Mechanical advantage is defined as the ratio of output force from a system to the input force into the system. A machine which has the mechanical advantage more than 1 means it requires less force to give more force as output. Similarly, when the mechanical advantage for the machine is less than 1,it means more force is required to give to achieve a less one.

Here in the question, the mechanical advantage of the pulley is 2.

Output force required to pull the sack of potatoes upto kitchen is 16N.

Mechanical advantage = Output force / input force.

Or, 2= 16 / input force.

So input force = $16 / 2 =8.$

So a force of 8 N will be required to pull the pulley.
