The energy that fuels food webs begins as light energy from the sun. True or False
lutik1710 [3]

Answer: i think its true. ( based of information i got)

Explanation: The Sun is the major source of energy for organisms and the ecosystems of which they are a part. Producers such as plants, algae, and cyanobacteria use the energy from sunlight to make organic matter from carbon dioxide and water. This establishes the beginning of energy flow through almost all food webs. also A food web consists of many food chains. A food chain only follows just one path as animals find food. eg: A hawk eats a snake, which has eaten a frog, which has eaten a grasshopper, which has eaten grass. A food web shows the many different paths plants and animals are connected.

Based on your observations, how does substrate concentration affect enzyme activity? (more than 1,
Norma-Jean [14]

Substrate concentration affect enzyme activity -

1. There is more enzyme activity at higher substrate concentrations due to more collisions between enzyme and substrate until a maximum rate is reached

2 Once the maximum reaction rate for the enzyme is reached, the reaction rate levels off.

The enzymatic reaction depends on various factors including temperature, substrate concentration, concentration enzyme, and other factors. The rate of a chemical reaction is affected by the total number of enzymes as well as the concentration of substrate

  • Increasing substrate concentration increases the activity of a corresponding enzyme
  • After a certain point, the rate of activity will cease to rise regardless of any further increases in substrate levels as the environment is saturated with substrate and all enzymes are bound and reacting to the maximum limit.
  • A high concentration of substrate causes increases in a collision between enzyme and substrate.
  • Collisions bring substrate molecules and enzymes together and increase enzymatic activity.

Thus, Substrate concentration affect enzyme activity -

1. There is more enzyme activity at higher substrate concentrations due to more collisions between enzyme and substrate until a maximum rate is reached

2 Once the maximum reaction rate for the enzyme is reached, the reaction rate levels off.
