Is it safe to assume that catabolic reactions are always exergonic and anabolic reactions are always endergonic?
Also, I had a question on energy metabolism. Since the mitochondria is where energy is stored, does that mean that metabolic (energy) pathways only occur in the mitochondria? Or is...
Below are some questions. I have struggled with these questions so any help would be greatly appreciated. Thank you so much.
The Earth orbits the Sun:
a. in a perfect circle
b.in an ellipse with the sun at the center
c.in an ellipse with the sun at the focus

an avalanche begins on a ski slope. the mountain is 30 degrees above horizontal. a skier is 100m downhill on path of avalanche
1. how much time does skier have to move out of way if no friction?
2. how much time does skier have if Uk is 0.1?
answer= 1. 6.4 s 2...
a 20 kg box is on frictionless surface acted on by two horizontal surfaces. when in same direction, it pulls 11 m/s but in opposite directions, it pulls only 1 m/s. determine magnitude of each force.
answer: 120 N , 100 N
okay...i need help with this. i am using Newtons law: force=mass x...
URGENT QUESTION: Chemistry
i would think that enthalpy of reaction would always have to be greater than activation in order to proceed. however, i thought the rest were false.
please help me...this is very frustrating.
This problem involves consideration of the following statements...
A merry-go-round of radius R=2.0 m has a moment of inertia I=250 kg m2, and is rotating at 10 rpm. A child whose mass is 25 kg jumps onto the edge of the merry-go-round, by jumping directly toward the center at 6.0 m/s. The new angular speed (in rpm) of the merry-go-round is approximately
A)...
