Science Test Ch.4

Most of the energy used by life on Earth comes from the sun
Organisms that are not autotrophs must consume other organisms to get energy
Light energy is converted to chemical energy through the process of photosynthesis
Which of the following organisms do not carry out photosynthesis animals
ATP is composed of a nitrogenous base, a sugar, and 3 phosphate groups
chloroplasts : photosynthesis :: mitochondria : cellular respiration
photosynthesis : oxygen :: cellular respiration : carbon dioxide
When cells break down food molecules, energy is stored temporarily in ATP molecules
ATP is called a cell's energy "currency" because ATP can be "made" in one place and "spent" or used in another
When a phosphate group is removed from an ATP molecule, a substantial amount of energy is released
Low temperature may cause photosynthesis to occur more slowly
When glycolysis occurs, a molecule of glucose is split
What is the net gain of ATP molecules in glycolysis 2
The name of the process that takes place when organic compounds are broken down in the absence of oxygen is fermentation
Fermentation enables glycolysis to continue under anaerobic conditions
Cells produce ATP most efficiently in the presence of oxygen
Which of the following processes produces the most ATP aerobic respiration
The ultimate source of energy for all life on Earth is the sun
Energy from the sun enters living systems through ______ such as plants and certain prokaryotes autotrophs
Animals get energy from food through the process of cellular respiration
Of the different inputs and products of photosynthesis, the most stable form of _____ is carbon dioxide carbon
Of the inputs and outputs of cellular respiration, the less stable carbon compound is glucose
Organisms extract energy stored in glucose through the process of cellular respiration
______ is the organic molecule that is the main energy source for cell processes and is made with the energy released from the breakdown of glucose ATP
______ is the energy "currency" of a cell ATP
During the first stage of photosynthesis, ______ is absorbed by chlorophyll light energy
The abundance of oxygen in Earth's atmosphere is a result of the process of photosynthesis
Why is chlorophyll green it reflects green
The cause of photosynthesis photosynthesis makes oxygen
Which of the following enables plants to light hydrogen ion pumps
The source of oxygen during production water
Products of dark reactions during photosynthesis ATP AND NADPH
During the final stage of photosynthesis, sugars are made from carbon dioxide
Fermentation enables glycolysis to occur under aerobic
The total amount of ATP depends on oxygen
Energy lost in the electron transport chain is used to pump hydrogen
During fermentation, alcoholic and carbon dioxide; other produces lactic acid
Glucose is split during what glycolysis

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.
