lecture 1 part 1

Question 1

bioenergetics

Answer 1

the study of the flow and transformation of energy

Question 2

different ways to think of bioenergetics

Answer 2

-can think of it within living organisms and between organisms and their environment
-how organisms/their cells acquire energy
-how energy is transferred to diff forms
-how organisms allocate and use their energy

Question 3

three aspects of bioenergtics

Answer 3

1)photosynthesis
2)movement
3)cellular respiration

Question 4

photosynthesis energy transformation

Answer 4

light energy -> chemical energy

Question 5

movement energy transformation

Answer 5

chemical energy -> mechanical energy

Question 6

cellular respiration energy transfer

Answer 6

chemical energy (sugar) -> other chemical energy (ATP)

Question 7

what do all organisms have

Answer 7

an energy budget

Question 8

energy budget

Answer 8

uptake and use of energy by an organism

Question 9

what must organisms do with energy

Answer 9

acquire energy from environment and allocate it to various life processes

Question 10

what are energy budgets about

Answer 10

resource allocation

Question 11

what impacts evolutionary fitness

Answer 11

how much energy organisms acquire and how they allocate itf

Question 12

fitness

Answer 12

contribution an individual makes (number of offspring) to the next generation relative to any other individual in a population

Question 13

are there trade offs between growth, reproduction and survival

Answer 13

yes

Question 14

more energy to one thing ______ energy to the other

Answer 14

decreases

Question 15

what comes with growth in terms of energy

Answer 15

increased need for greater energy intake

Question 16

what two things impacts an allocation of organisms energy

Answer 16

age and anrivonment

Question 17

prior to adulthood what is a lot of energy allocated to

Answer 17

growth
-still gives some energy to metabolism and repair

Question 18

after reaching adulthood how does energy allocation change

Answer 18

growth decreases and reproduction takes over as number onw

Question 19

what is another example of growth besides just getting bigger

Answer 19

acquiring fatty tissue such as with bears hibernating

Question 20

as organisms age energy investment in reproduction ___ as investment in repair ____. Why?

Answer 20

drops; grows
-things wear out, break down of DNA or mitochondria produce less enrgy

Question 21

lots of offspring

Answer 21

amount of energy per individual is small

Question 22

lots of offspring exmaple

Answer 22

mice

Question 23

few offspring exmaple

Answer 23

human

Question 24

few offspring

Answer 24

amount of energy per individual is large aka spending/investing more tome o caring fir young

Question 25

semelparity

Answer 25

organisms have one reproductive episode per life, they will die after giving birth and cant have more kids

Question 26

iteroparity

Answer 26

organism is capable of having multiple reproductive episodes per life
