Answer:
The correct answer is: 6 molecules of carbon dioxide are required in order to produce 1 molecule of glucose.
Glucose is synthesized in light-independent phase of the photosynthesis by cyclic process called Calvin cycle.
It takes place in the chloroplast and utilize ATP and NADPH produced in light-dependent phase of the photosynthesis.
Calvin cycle is divided into three parts: carbon fixation, reduction, and regeneration.
The cycle fixes 1 molecule of carbon per rotation. In addition, it requires 3 ATP and 2 NADPH in a single turn.
The cycle turns 6 times to produce one molecule of glucose. Hence, it requires 6 CO₂, 18 ATP, and 12 NADPH to fix one molecule of glucose.
The answer is 0.8 second. A cardiac cycle or also known as a
heartbeat approximately takes about 0.8 second to complete one cycle. A
heartbeat is fast since it is a muscle that pumps blood throughout the body.
The Cardiac Cycle has two phases, first the Diastole phase, wherein the heart
ventricles are relaxed, while the heart fills with blood, second is the systole
phase, wherein the ventricles contract and pumps the blood out from the heart
and takes it to the arteries to be
spread all around the body.
