Vera_Pavlovna [14]
Calculate the acceleration of a boat that has been cruising at 15 m/s but speeds up to 45 m/s in about 6 seconds. Don’t forget your units, m/s2. In order to calculate the acceleration of the boat we first have to identify the suited formula for acceleration in this scenario.

Hence, a = vf – vi / t. Vi = 15 m/s Vf = 45 m/s T = 6 seconds  

Solution:
A = 45 m/s – 15m/s / 6s
A = 5m/s^2

Part D - The effect of gramicidin on oxidative phosphorylation When the protein gramicidin is integrated into a membrane, an H c
Andrews [41]

Answer:

The correct answer would be -

Remains the same: proton pumping rate, electron transport rate, rate of oxygen uptake.

Decreases or goes to zero: rate of ATP synthesis, size of protein gradient

Explanation:

An H+ channel forms and the membrane becomes very permeable to protons if the protein gramicidin is integrated into a membrane. If gramicidin is added to an actively respiring muscle cell, it will affect the in the following manner:

Remains the same:

proton pumping rate, electron transport rate, rate of oxygen uptake.

Decreases:

rate of ATP synthesis, size of protein gradient

None of these will show an increase due to the addition of gramicidin tlo actively respiring muscle cells.

meriva
<span>Enzymes are used up as a part of the reaction and cannot be used again. Enzymes can be any shape to bind to the substrate. Enzymes are catalysts that lower the activation energy allowing the reaction to occur. Enzymes are formed into lipids. 3. Which macromolecule is most likely to be broken down for quick energy? nucleic acid carbohydrate phospholipid protein The Central Role of Enzymes as Biological Catalysts. A fundamental task of proteins is to act as enzymes—catalysts that increase the rate of virtually all the chemical reactions within cells. Although RNAs are capable of catalyzing some reactions, most biological reactions are catalyzed by proteins.</span>
