Lamilla wants to determine the rate at which a plant uses water. She fills a beaker with 80 mL of water and places a leafy flower stem in to the beaker through a small opening in the beaker's cap. Lamilla then places the beaker near a sunny window. One week later, 47 mL of water remains in the beaker. What plant process best explains the loss of water in the beaker?

*cant find

What is the balanced chemical equation for cellular respiration?

6CO2 + 6H2O → 6O2 + C6H12O6

The aerobic and anaerobic pathways of cellular respiration require which products of glycolysis?

ATP, pyruvate and NADH

While investigating yeast respiration, a researcher detects ethanol in the yeast culture. Which molecules does the yeast culture also contain?

Carbon dioxide and ATP

All organisms have ways to produce ATP. Which of the following statements describes why ATP is a critical compound for all cells?

It is an energy-transfer molecule.

What trait of an ATP molecule enables it to store energy for use by the cells?

Its phosphate-phosphate bond

Which of the following statements correctly describes the processes of photosynthesis and cellular respiration?

Photosynthesis stores energy for cells and cellular respiration releases energy for cells.

Which of the following is NOT a true statement about ATP?

Used ATP is discarded by the cell as waste.

Which of the following statements best describe how, in trees, water moves from the roots to the leaves?

Xylem contracts and pushes water and nutrients upward.

Energy is released from ATP when

a phosphate group is removed.

Which process do all organisms use to convert energy from food into ATP?

cellular respiration

Both photosynthesis and cellular respiration involve all of the following except

chlorophyll.

Select the processes that are matched with the incorrect amount of ATP produced by that process per glucose molecule.

citric acid cycle-4 ATP

The process that is most directly responsible for the majority of the ATP produced during aerobic respiration is which of the following?

electron transport chain

Which of the following is NOT a product of glycolysis?

glucose

Which of the following is the correct sequence of events in cellular respiration?

glycolysis → Krebs cycle → electron transport

Milk is converted to yogurt under certain conditions when the microorganisms in the milk produce acid. Which of these processes would you expect to be key in the production of yogurt? a. the Krebs cycle

lactic acid fermentation

Cellular respiration is called an aerobic process because it requires

oxygen

In biology class, Keesha places a suspension of the green algae Chlorella in a growth chamber. She turns the light on in the growth chamber, then measures the change in the amount of mc014-1.jpg in the growth chamber over the next 15 minutes. She then repeats the experiment, using a growth chamber that is devoid of light. She finds that the amount of mc014-2.jpg in the lighted growth chamber decreases over time, while the amount of mc014-3.jpg in the dark chamber increases over time. The most likely explanation for her results is that, in the absence of light, mc014-4.jpg

production by cellular respiration is greater than mc014-8.jpg consumption by photosynthesis.
