Photosyn&Respiration

QuestionAnswer
Living organisms maintain a constant balance of two opposing sets of metabolic reaction called... Catabolic pathways and anabolic pathways
Catabolic pathways Those that break down organic molecules for energy
Anabolic pathways those the build up organic molecules in store energy for later use
All living organisms perform some kind of ___________ ____________. Cellular respiration
Cellular respiration A chemical pathway in which organic molecules are broken down to release energy in a quickly usable from (ATP)
What are the two basic categories cellular respiration can be divided into? Aerobic respiration and anaerobic respiration
Aerobic respiration uses molecular oxygen as the final electron acceptor in the reaction pathway.
Anaerobic pathways Do not use oxygen as the perform respiration
Does fermentation use oxygen as it performs respiration? No
Aerobic respiration can be divided into 4 stages. What are the four stages? Glycolysis, the formation of acetyl CoA, the citric acid cycle, and oxidative phosphorylation
How many ATPs per glucose molecule does aerobic respiration make? 36 - 38
What's different between aerobic and anaerobic respiration? Aerobic uses oxygen and anaerobic does not.
Photosynthesis is the opposite of respiration. Light energy is converted into an organic molecule form such as glucose.
What are capable of performing photosynthesis? Plants, algae, and some kinds of bacteria.
Why cant animals perform photosynthesis? It's because their cells do not contain chloroplasts
The photosynthetic pathway can be divided into two stages called... Light dependent reactions and the carbon fixation reactions
Light-dependent reactions Occurs in the thylakoid membrane of chloroplast.
Carbon fixation reactions is also called the _______ __________ Calvin cycle
Carbon fixation reactions uses the energy in ATP and the NADPH to synthesize glucose.
What does rubisco do? It incorporates CO2 into Ribulose bisphosphate (RuBP)
During carbon fixation, the CO2 is _________ by the NADPH molecules and the energy for the energy requiring reactions is provided by ATP reduced
What does photorespiration sometimes do? It sometimes reduces the efficiency of photosynthesis.
The anaerobic process that is essential for making bread, cheese, ethyl alcohol, and some pharmaceuticals is called? Fermentation
Yeast contained in bread dough completes anaerobic respiration and causes the bread to rise. Which gas released by the yeast causes the bread to rise? Carbon dioxide

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
