Note: Question lack some information i have added full question with answer as picture. see attachment.
Answer:
d. In the first stage, macro-molecules are converted to monomers, and a small amount of ATP is produced.
e. In the second stage, monomers are broken down, and a small amount of ATP is produced.
c. In the third stage, fuel molecules are completely oxidized to CO2, and no ATP is produced.
Explanation:
When we take food a process starts which is called as cellular respiration. Through this process the food energy is converted into cellular energy which will further used by body. During all this process oxygen and glucose are converted into water and carbon dioxide and energy in this process is converted into ATP.
Answer:
-During citric acid cycle or Krebs cycle, radioactive carbon will be first appear in citric acid
Explanation:
During cellular respiration, glucose is first converted into pyruvate molecules by the process of glycolysis. These pyruvate molecules go for oxidative decarboxylation, during which acetyl co-enzyme A (acetyl CoA) is formed along with removal of carbon dioxide.
The acetyl co-enzyme enters to the next step in cellular respiration or citric acid cycle or Krebs cycle. The first step of citric acid cycle is formation of citric acid by joining of acetyl CoA and oxaloacetate.
As citric acid is first molecule formed during citric acid cycle, radioactive carbon would be first appear in citric acid.
I assume that in this item, we are asked to solve for the force exerted during the heartbeat. Force is the product of the mass and acceleration. To solve for the acceleration in this item, we divide the velocity by time.
a = 1 m/s / 0.2 s = 5 m/s²
Then, we multiply this by the mass (in kg)
F = (80 g / 1000 g/kg) x (5 m/s²)
= 0.4 kg m/s² = 0.4 J
Therefore, every hearbeat will take 0.4 J of force.
