Drag the correct word from the left into the sentence on the right to complete each sentence. In anabolic reactions that involve

kkurt [141]

Answer:

The correct matches are:

In anabolic reactions that involve the synthesis of a large molecule from smaller precursor molecules, NADH and ATP are consumed when they provide the needed electrons or energy.
In catabolic reactions that involve the breakdown of a molecule into smaller subunits, such as glucose to pyruvate, NADH and ATP are produced.
In the reaction Pyruvate +NADH-Lactate +NAD, pyruvate is being reduced.
In the reaction Pyruvate NADH-Lactate +NAD, NADH is being oxidized.

Explanation:

Being involved in synthesis, anabolic reactions require energy in the form of energy storing molecules such as NADH and ATP. Anabolic processes utilize energy produced by the catabolism of complex compounds.
Catabolic processes produce energy or energy storing compounds by breaking down complex substances into simpler ones. All steps of cellular respiration are catabolic processes since they generate energy in the form of ATP or energy yielding molecules such as NADH and FADH2.
Anaerobic respiration takes place during intense physical activity due to which adequate oxygen does not reach the cells. Insufficient oxygen shuttles the pyruvate molecules produced by glycolysis into the lactic acid pathway that reduces pyruvate into lactic acid.
Since, NADH is donating its H+, it is being oxidized to NAD+.

How does capillarity help sustain life? a. plants use capillarity to move water from their roots to their leaves. b. capillarity

bazaltina [42]

Answer:

Explanation:

Plants and trees couldn't thrive without capillary action. Capillary action helps bring water up into the roots. With the help of adhesion and cohesion, water can work it's way all the way up to the branches and leaves.

Suppose you ate an entire bag of potato chips and drank a 16-ounce cola while you studies for an exam. Together these items cont

Anastaziya [24]

Answer:

Total of $1164.187$ kilo-calories are consumed.

Explanation:

In order to determine the total calories present in any food item, the calories contribution of each of its constituents must be know.

Here,

Calories in one gram of carbohydrate $= 4$ kilocalories

Calories in one gram of protein $= 4$ kilocalories

Calories in one gram of fat $= 9$ kilocalories

As per the details provided on Coca-Cola website, calories in 16-ounce cola $= 187$ calories $= 0.187$ kilocalories

Thus, total calorie in an entire bag of potato chips and 16-ounce cola

$(144 * 4) + ( 12 * 4) + (60 * 9) + 0.187\\= 576 + 48 + 540 + 0.187\\= 1164.187$

Total of $1164.187$ kilo-calories are consumed.

Which of the following statements are true about enzymes? Select all that apply.

Andrews [41]

Answer:

2, 3 and 5

Explanation:

Enzymes lower the activation energy, making life possible to occur as the reactions can happen quickly. But, they can be affected by temperature or pH, and they are always being constantly reused over and over in reactions.
