Louis, MO We are open Saturday and Sunday! Subject optional. Email address: Your name:. Explanation : FADH2 is directly attached onto the second protein of the electron transport chain and therefore the electrons of FADH2 electron carrier are dropped off at the second protein not the first.
Report an Error. What driving force creates most of the ATP in cellular respiration? Correct answer: the movement of protons down its concentration gradient. Which process occurs in both cellular respiration and photosynthesis? Possible Answers: Calvin Cycle. Correct answer: chemiosmosis. Explanation : In both cellular respiration and photosynthesis, chemiosmosis occurs. Possible Answers: Exocytosis. Correct answer: Apoptosis. Explanation : Apoptosis is programmed cell death, and it usually occurs when the DNA of the cell is damaged beyond repair.
Example Question 1 : Cellular Division. Possible Answers: The S phase. Correct answer: The M phase. Explanation : The M phase is also known as mitosis, and is the time where the cell is ready to divide.
Which of the following describes cell activity during the G 1 phase of the cell cycle? Possible Answers: The cell undergoes mitosis. The cell increases in size and produces new organelles. Correct answer: The cell increases in size and produces new organelles. Explanation : During G 1 , the cell undergoes growth as it increases in size and produces organelles. Example Question : Ap Biology. Which of the following phases of the cell cycle make up what is known as interphase?
Possible Answers: G 1 , G 2 , and M. Correct answer: G 1 , S, and G 2. Explanation : Interphase in the cell cycle encompasses the G 1 , S, and G 2 phases, as it shows the period of growth and DNA replication that a cell must go through to prepare for mitosis. Possible Answers: S. Correct answer: G 0. Explanation : Because they do not divide, central nervous system nerve cells do not need to experience growth G 1 and G 2 phases , DNA replication S phase , or mitosis M phase. Possible Answers: M.
Taking the human body into consideration, we need energy in form of ATP for running normal bodily functions and movements, where does the energy come from? Food, alright. When we eat food, there occurs digestion in the gut, the food molecules are then absorbed into our cells, this is called primary metabolism.
Mitochondrion plural: mitochondria is the powerhouse of a cell, it is responsible for the production of energy in eukaryotic cells in the form of ATP.
Ovoid in shape, it has a matrix enclosed by an inner selective membrane and an outer more permeable one, the two membranes are separated by the intermembranous space. The inner membrane has in-foldings called cristae which exhibit a high degree of selective permeability and serve as the home for a group of enzymes and co-enzymes constituting the electron transport chain , this chain is where FADH 2 and NADH are used to produce the ATP.
Cellular respiration produces 36 total ATP per molecule of glucose across three stages. Breaking the bonds between carbons in the glucose molecule releases energy. There are also high energy electrons captured in the form of 2 NADH electron carriers which will be utilized later in the electron transport chain.
Pio Otaegui Supporter. How many ATP are formed in aerobic respiration? Zoubir Saur Supporter. What is the net gain of ATP during glycolysis? Overall, the process of glycolysis produces a net gain of two pyruvate molecules, two ATP molecules, and two NADH molecules for the cell to use for energy. Therese Hagge Supporter. What are the three products of cellular respiration? Oxygen and glucose are both reactants in the process of cellular respiration. The main product of cellular respiration is ATP ; waste products include carbon dioxide and water.
Raj Mollfulleda Beginner. What produces the most ATP? So, oxidative phosphorylation is the metabolic cycle that produces the most net ATP per glucose molecule. Here is the breakdown of net ATP production:. Glycolysis: 2 ATP. Krebs Cycle: 2 ATP. Fermentation: 2 ATP. Mahamadou Ottemeyer Beginner. What are the net products of glycolysis?
