Q. What enters mitochondria during respiration?
In the presence of oxygen, under aerobic conditions, pyruvate enters the mitochondria to proceed into the Krebs cycle. The second stage of cellular respiration is the transfer of the energy in pyruvate, which is the energy initially in glucose, into two energy carriers, NADH and FADH2.
Q. What are the outputs of cellular respiration?
Unit 5: Photosynthesis & Cell Respiration
| Question | Answer |
|---|---|
| What are the inputs of cellular respiration? | Glucose, oxygen |
| What are the outputs of cellular respiration? | Carbon dioxide, water, energy (ATP) |
| What is the site of cellular respiration? | Mitochondria |
Q. What are the 2 inputs and 3 outputs of cellular respiration?
The inputs, or reactants, of cellular respiration are glucose and oxygen. The outputs, or products, of cellular respiration are water, carbon dioxide…
Q. What two places does cellular respiration occur?
Aerobic vs anaerobic respiration
| Aerobic | |
|---|---|
| Products | ATP, water, CO 2 |
| Location | Cytoplasm (glycolysis) and mitochondria |
| Stages | Glycolysis (anaerobic), Krebs cycle, oxidative phosphorylation |
| ATP produced | Large amount (36 ATP) |
Q. How does cellular respiration work?
Cellular respiration, the process by which organisms combine oxygen with foodstuff molecules, diverting the chemical energy in these substances into life-sustaining activities and discarding, as waste products, carbon dioxide and water. …
Q. What can stop cellular respiration?
ATP, ADP, and NADH are examples of molecules that regulate cellular respiration enzymes. ATP, for instance, is a “stop” signal: high levels mean that the cell has enough ATP and does not need to make more through cellular respiration.
Q. What is a sentence for cellular respiration?
2. Much of the o 2 supporting cellular respiration is reduced to the superoxide anion o 2 -. 3. Cellular respiration is the chemical reaction that helps a person to turn the sugar in food into energy.
Q. What process begins cellular respiration & does it produce much ATP?
glycolysis
Q. Does bacteria perform cellular respiration?
Many prokaryotes, small simple cells like bacteria, can perform aerobic cellular respiration. These cells will move electrons back and forth across their cell membrane. Other types of prokaryotes cannot use oxygen to perform cellular respiration, so they perform anaerobic respiration.
Q. What are two reactants needed for cellular respiration?
Glucose and oxygen are the reactants and the end products are carbon dioxide and water with the liberation of energy in form of ATP.
Q. Where does aerobic cellular respiration occur?
mitochondria
Q. Which correctly shows the order of steps in aerobic cellular respiration?
Aerobic cellular respiration can be broken down into three main steps: glycolysis, the citric acid cycle (the Kreb’s cycle ), and electron transport. Glycolysis occurs in the presence of oxygen and is when glucose is broken down. This occurs in the cytoplasm.
Q. Which of the following shows the advantage of aerobic cellular respiration?
A major advantage of aerobic respiration is the amount of energy it releases. Without oxygen, organisms can split glucose into just two molecules of pyruvate. This releases only enough energy to make two ATP molecules. With oxygen, organisms can break down glucose all the way to carbon dioxide.
Q. Which stages of cellular respiration use O2 as an input?
O oxidative phosphorylation O citric acid cycle and oxidative phosphorylation O glycolysis and oxidative phosphorylation O glycolysis, pyruvate oxidation, and the citric acid cycle O All four stages use O2 as an input.
Q. Which of the following steps in cellular respiration does not occur in the mitochondria?
So, if you are asked to identify the stage (or stages) of cellular respiration that occurs entirely outside of the mitochondria, you can answer “glycolysis” and be done with it.
Q. What process happens in the mitochondria?
Mitochondria, using oxygen available within the cell convert chemical energy from food in the cell to energy in a form usable to the host cell. The process is called oxidative phosphorylation and it happens inside mitochondria. In ATP the energy is stored in the form of chemical bonds.
