Answer: A
Explanation:
The nucleus provides the instructions for making the proteins (the DNA) and the ribosomes are actually where the proteins are made.
its actually false true is wrong
Autonomy vs shame and doubt
The autonomy vs shame and doubt age is a phase during the development of children. It occurs between the ages of 18 months and three years old. During this stage, the children start to become more independent and start making some of their own decisions. These decisions include what to wear, what to eat and what to play with. Having overbearing parents hinders the development of this stage of development.
Answer:
Explanation:
1- the purpose of blood flow-circulatory system- is to convey Oxygenated blood, oxygen bonded with haemoglobin in the RBC with Nutrients - and distributed these through the arteries and capillaries away from the heart, to reach the cells and tissues, and transported the wastes of theses cells and tissues , with C02 through the veins back to the heart and the kidney.
2. During diastole,deoxygented blood from the inferior and superior vena cavae entering the R.atrium, passes through the tricuspid valve into the Right Ventricle. Simultaneously, oxygenated blood returning through the pulmonary veins enters the left Atrium,emptied through the bicuspid valve into the Left.Ventricle.
During systole, the two ventricles contracts. The Right ventricle contracts, the pressure of the blood forces the tricuspid valve to close,and therefore de -oxygenated blood pushes the pulmonary valves to open and blood passes through the pulmonary artery to reach the lungs where exchanges of oxygen with carbon dioxide occurs.The blood is now oxygenated and returns to the left atrium via pulmonary veins.
Simultaneously, the left ventricle contracts,the oxygenated blood it contains forced the bicuspid valve to close so that blood is forced through the aortic valve to empty into the aorta into the systemic circulation,branches of the carotid artery supplies the heart from the aorta.
The Whole cycle continues.
The true statements are:
- Substrate level phosphorylation ocvurs during Pyruvate oxidation
- 32 ATP molecules can be made by cellular respiration but only 2 ATP molecules when oxygen is lacking
- Electrons move from protein to protein due to increasing electronegativity in the electron transport chain
- ADP is phosphorylated in the matrix of the mitochondria during oxidative phosphorylation
- ATP inhibits pyruvate dehydrogenase by feedback inhibition
<h3>What is glucose oxidation?</h3>
Glucose oxidation refers to the process in the cells in which glucose molecules are oxidized to form ATP and carbon dioxide in the presence of oxygen.
The first stage of glucose oxidation is the conversion to pyruvate.
Pyruvate is oxidized to acetylCoA.
AcetylCoA enters the citric acid cycle to produce reducing equivalents, NADH for the electron transport chain.
- The true statements about pyruvate oxidation is that there is substrate level phosphorylation during the process
- When there is sufficient oxygen, 36 ATP molecules can be made (theoretically) by cellular respiration. However, when oxygen is lacking, only 2 ATP molecules are made.
- In the electron transport chain of cellular respiration, electrons move from protein to protein due to increasing electronegativity
- During oxidative phosphorylation, ADP is phosphorylated in the matrix of the mitochondria
- Aerobic respiration can be regulated by feedback inhibition of pyruvate dehydrogenase by ATP.
